How to measure without a ruler

When we measure length when there is not a ruler, we may.

For example, the size of a bank card is generally mm.

inch), if in the office, we can also use A4 paper to replace, generally speaking, the size of A4 paper is 210*297mm, and the most commonly used RMB, to the most commonly used now.

For the five sets of renminbi (the red version is the fifth set), the 100 yuan note is 155 mm long and 77 mm wide, the 50 yuan note is 150 mm long and 70 mm wide, the 20 yuan note is 145 mm long and 70 mm wide, the 10 yuan note is 140 mm long and 70 mm wide, the 5 yuan note is 135 mm long and 63 mm wide, and the 1 yuan note is 130 mm long and 63 mm wide. Therefore, when we don't have a ruler, we can choose the commonly used items around us for comparison, and we can measure the length without a ruler. If it is inconvenient to compare items, **ruler** also provides a free**ruler service, **ruler scale is accurate and easy to measure, and it is an ideal tool for you to measure the length without a ruler.

In the absence of a ruler, this makes it possible to measure the healthy distance from looking at a phone or computer.

If you don't have a ruler, you can use the software that comes with your phone to measure the size. References can also be borrowed.

to measure the size, for example, the size of a bank card is usually ; A4 paper size.

It is 210 297mm. There are four steps in total, and the following is the detailed operation:

Steps.

Open the Measure tool.

Open the mobile phone comes with a measurement tool, usually there are two units of the measurement tool, one is cm, the other is in, select the "cm" unit.

It is denoted by "m".

Use a rope to measure it from beginning to end, and use the rope to draw out the display size of a mobile phone screen, which is represented by "m".

Represented by "n".

Then fold the rope in half, fold it in half several times, and record the total number of segments after folding, which is represented by "n".

According to the calculation formula, the length l=m*n, the length of this section of rope can be calculated.

If you don't have a ruler, you can use some common items to roughly estimate the length, such as: 1Use your fingers to estimate the length:

Spread your fingers and use the length of your fingers to estimate the length of the items in the auction hall, which gives you a rough estimate of the length of the Great Debate. 2.Use paper tape or thread:

You can also roughly estimate the length of the shirt by measuring the desired length of paper tape or thread and comparing it with a ruler or other item of known length. 3.Use body parts:

For example, estimate the length of an item using the length of a foot, hand, arm, etc. Please note that these methods are rough estimates and may contain errors, and if more accurate length measurements are required, it is recommended to use a professional measurement tool.

If you don't have a ruler, you can use other items to measure the length. Here are a few common methods:1

With fingers: Place objects in the palm of your hand and use your fingers (e.g. index finger, middle finger, etc.) to count them one by one according to their length. 2.

Step counting: Lay an object flat on the ground and measure its length with your steps. Each step is about 50 to 70 centimeters, and the length of the object can be deduced from the number of steps.

3.Wire and rope comparison method: use a thread or rope to go around the length of the object, and then compare the rope with a standard length of wire (such as a piece of rope of known length, cloth strip, etc.), and then delay the slip to calculate the length of the object.

4.Relative Comparison Method: Comparing an object to an object of known length.

For example, the length of an object can be deduced by comparing it to a standard-sized piece of paper or a pen.

withRemember the rice wheelMeasurement.

You can use a meter wheel to roll on the object to be measured, and roll it through the counter.

The number of turns of the capacitance is recorded, and finally the length of the entire measured object is calculated. The advantage is that the equipment cost is low and the initial measurement is accurate. Cons:

After more than a week of continuous use, the accuracy will be reduced due to the wear and tear of the rollers, and when it is used for more than a month, the accuracy will become undesirable.

We can't do without mobile phones in our lives, we can't do anything without mobile phones when we go out, as the functions of mobile phones become more and more, it has become more powerful, so can mobile phones be used to accurately measure the size of an object? The answer is yes, now teach you how to measure the size of an object with your mobile phone.

There is a problem with the need to measure the size of the ruler.

This measuring widget can choose the functions of ruler, angle ruler, level and so on.

Ruler: Just aim directly at the object you want to measure the length of and look at the scale.

Angle ruler: Align one side of the object to be measured at the center line to see the scale.

You don't need to measure the length with a ruler, turn on the small function of the mobile phone, and you will know the result at once.

With the amount of footsteps, many surveyors do this in the field, and the standard step distance should be 75cmThe specific varies from person to person, and everyone's step distance is relatively fixed.

For example, measure with your hands! Measure with A4 paper.

If you don't have a ruler, you can use the software that comes with your phone to measure the size. It is also possible to measure the size by reference objects, such as the size of a bank card; The A4 paper size is 210 297mm. A total of four positive orange steps, the following is the detailed operation:

End summary: The above are the specific operation steps on how to measure the size without a ruler, I hope it will be helpful to the large empty group.
