How to measure centimeters without a ruler. How to take measurements for clothes without a centimeter tape. When there is absolutely nothing at hand

Measurements without a ruler!

Sometimes, situations arise when you need to measure a certain length at least approximately, but there are no necessary measuring instruments at hand. For these purposes, there are many ways that you can use to measure length and distance. The very first, and well-known, method that requires only knowledge of your height, measuring the distance "in parrots" (by analogy with the well-known cartoon). The presence of a leaf in a box speaks for itself. Knowing the length of the foot, you can also use it, if only just to measure the required longer segment on the stick, and with the help of it (the stick) take measurements according to the principle: pyramid of measurements. Rope, wires, or similar flexible materials can be measured by holding them at your fingertips. To do this, it is necessary to take any straight arm to the side, and bend the other at the elbow and direct it in the same direction of the abducted arm. Thus, we get the distance from the tip of the ring finger of one hand to the tip of the ring finger of the other hand, equal to approximately one meter. You can use coins or banknotes, unless of course you know their diameters or sizes, the only difficulty is remembering them. If the iPhone is in your pocket, then you can measure the distance not only with the iPhone itself knowing its length, but also use mobile applications specially created for this purpose (Apple-o-Meter, etc.).

The approximate distance or length, with a small error, can always be determined.

Comments

You can still measure degrees with an iPhone. Not in alcoholic beverages, of course (I have not yet heard about such a program for him), but the angle of inclination. By measuring the circumference with an iPhone, you can calculate the diameter using the iPhone again)). So on such a device, it is better not to save.

That's an ambush, and what am I going to do with my Highscreen? (((I have a compass there, and a tape measure. And a protractor, and a level, and somehow they don’t come in handy. Got it! If it were an iPhone, it would certainly come in handy. You must definitely justify such things, otherwise why take it? ???!!!

That's the point, when you need it, no, when you don't need it, you have it)). Also, everyone has the same passport in size, also an option. Like iPhones-dollars, you also always have to carry it)))

How can you measure length or distance yourself?

I will supplement the answers of consultants and offer a few more simple ways for measuring.

For example, a chain is a male and female jewelry. All chains usually have different length which is indicated on the label. So, for example, with a chain of 50 cm, you can even measure the length and height of the walls. Moreover, using the chain, you can calculate the area of any surface.
Or shoelaces. As a rule, all laces have a certain length, so by pulling out just one lace (and if two laces are tied together, you can get a whole meter), they can measure anything.

And the simplest ways to measure length are human hair; pillowcase (one side is usually 60 cm); table (if you know its size, you can attach something - for example, women's tights, measure desired length, and then measure them); passport; driver's license; metro pass, credit card. And many, many other ways.

Everyone in their life faced with a situation when it is necessary to measure something. That's just according to some law of injustice, at this very moment, neither a tape measure nor a ruler is at hand. But in fact, everything is not at all as hopeless as you think. You can find a way out of this ridiculous situation and call for help with improvised means. For creative people who work all the time at the computer, a centimeter ruler is useful online.

There is a moment when there are absolutely no auxiliary objects nearby. When not standing, he forgets about the elementary - arms and legs, can also become good meters.

If you look at the open palm, then on each finger we will notice three approximately identical phalanges. Based on the English system of measures, we come to the conclusion that its length is one inch, approximately 23-37 mm. Therefore, having set a goal, you can produce personal sizes. So you will know the exact length of your phalanx and will be able to put this knowledge into practice. You can also take measurements with your foot. Having previously learned how much it is in centimeters.

Handy items to help

Each monetary currency has its own specific sizes. Deviations in them definitely can not be. Thus, knowing the sizes of various denominations, you will not be reached by mistake.

The passport is not only a certifying document, but also a kind of ruler; its size is 88 × 125 mm. Even ordinary things that are constantly around us can make error-free measurements. For example, 1 meter = forty 5 ruble coins in a row, or 8 passports stacked in height.
If you still have a ruler at hand, but only it is so small that it seems simply impossible for her to measure large-sized things.

Here are some great options for measuring objects or distances without a ruler:

1. You can go in parallel. It is necessary to apply a ruler to the object being measured over and over again. Of course, this procedure will take a lot of time, but the result will be accurate. The main thing is to leave small marks when taking measurements, this will help you not to deviate from reality.

2. There is also an indispensable pyramid method. It is based on the fact that first you need to measure some small object, and then use it to start measuring the right thing. Moreover, the number of objects involved in such a process can be a huge number.

3. Wheel method, a great helper for measuring length. It is only necessary to take something round to measure its radius. Then he makes notches on it and the measured surface, then we twist it, counting circles. The resulting amount is multiplied by 2 "pi".

You can also resort to using a mobile phone and say a special offer on it. Everything turns out to be very simple, now you definitely won’t get confused if you need to measure something.

Probably, everyone is familiar with the following situation: there is neither a ruler nor a tape measure at hand, but something needs to be measured and urgently. How to measure distance or diameter if there is no measuring tool at hand is the topic of this article. We’ll make a reservation right away that the idea is not new, but for beginners and lovers of making something, it can come in handy.

If you look, then almost any object can be suitable for measurements. For example, you needed to measure the width of the countertop, you mark the distance with the first object that comes across (let it be at least a spoon, at least a chain from the neck), and then with the help of a ruler you will find out the length of this very spoon or chain. But sometimes there are objects whose dimensions are standard. Knowing them, you can immediately start calculating without measuring these items later.

computer disk

Not all of us carry discs with us in our pocket, but still this item is quite common: at home, at work, in the car. Interestingly, its indicators of the outer and inner diameters are integers. For example, the inner diameter of the hole is exactly 15 mm, and the overall diameter of the disc is 120 mm. But that's not all: with the help of a disk, you can measure the wheels using the so-called method. Its essence is as follows: a mark is made on the edge of the disk with a pencil, marker, or a notch is made. Next, you set the disk with a mark to point A (where you need to start measuring) and roll it like a wheel to point B. In this case, you need to follow the given mark on the disk, counting its full revolutions. And then we apply a simple formula to find out the circumference: π*D. That is, we multiply the famous 3.14 by the diameter = circumference, then multiply by the number of full revolutions = length. If we are talking about a disk, then 3.14 * 120 \u003d 372 mm is the length of its circumference. One turn - 37 cm, two turns - 74 cm, three - 111 cm and so on.

The wheel method, by the way, works very well when measuring long distances with a bicycle.

A standard cigarette is usually listed as 80mm long. There are other values (70 mm, 100 mm and even 120 mm). When measuring, we got 83 millimeters. If you smoke, there was no ruler at hand, and you need to measure a relatively small distance, then a cigarette will help you do this.

Notebook sheets

A checkered sheet is probably the most convenient way to measure the length of something small. Just put an object on such a sheet and count the number of cells that this object closes. One cell - 5 mm.

If the notebook is in a line, then there is an indicator of the distance between the lines of 11 mm.

Glass jars in any country of the post-Soviet space are standard. That is why we can recommend them as such a line. Three-liter jar has a height of 23.5 cm, a liter - 16 cm, and a half-liter - 11.7 cm. By the way, the neck of any of these cans has the same diameter indicator - 8.2 cm.

Matchbox

I remember that this method was used a very long time ago. What is good about a box of matches is that it has a standard length of 5 cm. And it is convenient to calculate, and the box itself can be found on every corner.

bank card

The standard card sizes of any bank suggest that this item is convenient for measuring something. The sizes are indicated in the photo and believe that your credit card does not differ in terms of length and width. Maybe the content, but that's another story J.

Mobile phone

What is the most convenient way: everyone has a mobile phone and almost always with them. If you know her dimensions, then you can measure it with your phone. For example, the old Samsung in the photo helped the owner out a couple of times. We believe that finding out the height and width of your phone once is not such a big deal, but then, remembering the indicators, it will help you out. Still better than nothing.

Using our body

Our great-great-great-ancestors used their body parts to measure the length of something. For example, a span is the distance between the tips of the index finger and the thumb and is 17.7 cm. The photo shows that the owner of the hand has this distance of 19 cm. » will not give an error for many years. Unless the wrong rearrangement of the fingers when measuring can make a difference, but still better than measuring with a jar, spoon or string.

You can use your step, foot length, elbow, fingers - almost the entire body will serve as a "roulette". Just measure a part of your body in advance, remember this value and you are already a walking ruler.

Instead of a conclusion

A simple example: a man was looking for mushrooms in the forest and at the same time found an interesting blank for some of his crafts. It seems to fit the eye, but the eyes can fail. Carry a piece of wood all the way with you - what if it turns out later that it doesn’t fit? Finger, mobile phone or a knife (if you know its length) will help you immediately understand whether the found workpiece is suitable or not. Maybe the example is not entirely successful, but still not fantastic - everyone can have something similar happen. Not in the forest, but in another place where there is no ruler, no tape measure, no caliper.

Whether you need to determine the size of your finished garment from a size chart, or you just want to sew something for yourself or someone else, taking the right measurements is the key to a perfect fit for any item. It is best to take measurements with a special centimeter tape, but if you do not have it on hand, you can use other tools at hand.

Steps

Choice of measuring instruments

Look for something flexible to take measurements. Try to find something flexible at home that you can easily wrap around your body to take measurements.

Try using available materials such as yarn, twine, scraps of fabric, or wire.
The material you choose should not be of great value to you, as you will have to mark it with a centimeter scale, cut or otherwise damage it in order to make it easier for you to take measurements.

Find an object with exactly the length you know. Look for an item with a straight edge that you know the exact length of. Depending on the specific item, you can either use it as a measuring tool or measure other material such as twine with it.

Apply a scale with centimeter marks to the selected material for measurements. If you do not know the exact length of the object chosen instead of the centimeter tape, take a ruler and put a centimeter scale on it.

To take measurements, attach an improvised centimeter tape to the body. Attach the prepared measuring material to the part of the body that you are going to measure in order to determine its length, based on the centimeter marks applied to the material or from knowing its exact dimensions.
- If the material being used is too short to measure the required length, place your finger as accurately as possible at the point where the material ends, and attach it (material) to this point again to continue measuring. Do this as many times as needed to complete the measurement.
- If you want to first find out the length of a body part and only then measure it in centimeters, attach the measuring material to this part of the body and mark on it with your fingers the place (or, if you use string, even cut the material in the place) where the required length ends. Then take a ruler or use your hand measurements to find out the length of your measurements.
- Be sure to write down all the measurements received and do not forget to sign what the numbers you specified refer to.
Taking measurements for women's clothing
1. Measure your bust. To determine your chest circumference or the chest circumference of another woman, it is necessary to draw the measuring material around the body along the shoulder blades, under the armpits and along the most protruding part of the chest.
  
  Determine your waist circumference. Take the measuring material and determine the girth of the natural waist - the narrowest point of the body. To determine the location of the waist, look in the mirror and pay attention to the part of the body that is just above the navel, but below the chest.
  
  Measure around your hips. To determine the circumference of your hips, wrap the measuring material around the widest part of your hips.
  - Usually the widest point of the hips is 20 cm below the natural waistline, however this parameter varies from person to person. You can take several different measurements to pinpoint the largest one.
  - If you are measuring yourself, be sure to check in a mirror that the measuring material runs horizontally around the hips and buttocks.
2. Find out the length of the inseam. To determine the length of the inseam of trousers, it is necessary to measure the distance along inside legs from crotch to ankle. The leg must remain straight.
  
  If necessary, take additional measurements. Use the measuring material to take any other measurements that are listed in the finished garment size chart or needed to fit the pattern.

Without measuring ruler or measurement with bare hands

GBOU gymnasium No. 406, 5 "g" class

Bobrovskaya Svetlana Ivanovna

To date, there is not a single profession and even a school subject where nothing needs to be measured with the help of instruments or by eye, that is, without instruments.

Well, of course, we all have houses measuring instruments. This is a watch that tells you when you have to go to school and when your favorite TV show starts; a thermometer, which everyone will surely glance at when going out into the street; electricity meter and more.

Have you ever had such a situation: you need to measure something, but there are no rulers, tape measures and other measuring tools within reach?

If you have absolutely nothing at hand, you have at least arms and legs!!!

And, although we are all different, on average, some parts of the body of all of us are quite close in size.

For example, there was such a situation: they bought a TV. Dad knew the dimensions of the trunk of the car (length, height, depth), and he measured the dimensions of the box with his hand, or rather, the distance between the thumb and forefinger, i.e. span.

Why is this topic not relevant, if without any tools, you can measure the height of a box, pillar, pyramid, tree, etc.

Problem: Is it possible to measure objects without standard measuring instruments.

Target: justify the importance of measuring different quantities without measuring instruments.

Tasks :

Analyze the literature on ancient measures of length

Compare and summarize the need to use non-standard measures of measurement.

Conduct a peer survey

Reveal the presence or absence of interest in my project

Hypothesis : Suppose you need to measure something, but there is nothing at hand. A person in his life can measure any length and distance without using measuring instruments.

The first units of measurement were not very precise. For example, distances were measured in steps. Of course, different people the step size is different, but some average value was taken. For measuring large distances, the step was too small a unit. Therefore, in ancient Rome, for such measurements, mile (this is a path of 1000 double steps, both right and left foot).

And even greater distances were measured transitions or travel days. In Jack London's story "White Silence", the Indian, when asked how much is left to travel, answers: "You drive 10 dreams, 20 dreams, 40 dreams", i.e. days. Estonian sailors measured the distance tubes . So they called the path traveled by the ship at normal speed during the time that a pipe stuffed with tobacco was being smoked. In Spain, the same measure of distance was cigar, and in Japan - horse shoe. This was the name of the path taken by the horse until the straw sole tied to its feet, which replaced the horseshoe in this country, was worn out.

One of the most common units of length was elbow , i.e. distance from the elbow to the end of the middle finger.

But the elbows of different people have different lengths. Therefore, in each city, the king who ruled them issued a decree which elbow should be used by all his subjects. And when the small kingdoms merged into one large state, then the appropriate instructions came from the capital.

A measuring ruler is not always at hand, and it is useful to be able to somehow manage without it. The easiest way to measure long or short distances is in steps. To do this, you need to know the length of your step. Of course, the steps are not always the same, but still we can know their average length. To do this, you need to measure the length of many steps together and calculate the length of one from here. Another old rule refers to walking speed: a person walks as many kilometers per hour as he takes steps in 3 seconds !!!

In theory, everything is clear, but in practice there was such an experiment: to measure the length of the car. Measure your stride length with a tape measure. It is equal to 70 cm. The length of the machine according to the technical data sheet = 431 cm. According to measurements, the length of the machine is 6 steps, i.e. 420 cm. There is an error.

Measurement with the palm, more precisely the width of the hand

IN Ancient Rus' small objects were measured with the palm of the hand, and in English stories one can often find a description of how a peasant or horse lover determined the height of a horse by the number of palms. Knowing the size of your desk, measuring it with your palms and span. Happened:

Table length = 200 cm.

table length = 12 spans * 16 cm = 192 cm;

table length = 24 palms * 9cm = 216cm

We will also measure the door in our room:

Height door frame= 25 palms or 13 spans

Door frame height (data from the store) = 210 cm

These experiments will interest everyone and you can measure everything around! Starting from classmates and ending with a sandwich!

Fathom = growth;

sandwich = 6 coins of 10 rubles.

MEASURE means to find with the help of special technical devices the value of some physical quantity. At the same time, it is compared with the same-named value, taken as a unit.

Measurement is one of the most important things in modern life. The first units for measuring quantities were not very accurate. In Russia for a long time there were many different sazhens, a palm, etc. The modern unit is mm, cm, dm, meter, etc.

"What does it mean to measure?" In short, you can answer like this: “To measure means to compare with the standard.” IN Everyday life the measuring standard must always be available. For a student, a textbook can serve as a standard, as well as a “live scale”, for example, the width of a nail, or the length of the index finger. It can be seen that the "live scale" is more acceptable.
