Before using the scale, it must be ensured that the scale scale is clearly visible without damage or deformation. At the same time, the measured object needs to be placed on a flat horizontal surface to ensure the accuracy of the measurement results. Align the zero scale line of the ruler with the starting point of the object to be measured.
Ensure that there is no gap or overlap between the scale and the object to avoid measurement error. Record the measurement results, which can be expressed by unit symbols, such as "cm" or "mm". At the same time, in order to avoid forgetting or confusion, it is best to associate the measurement results with the name or logo of the measured object.
One centimeter
The centimeter (cm) is an international unit of length and belongs to the metric system. Centimeter is one of the units of length, expressed in centimeters. It is one hundredth of a metric unit of length, which is equal to one hundredth of a meter. Centimeter is a very small unit of length, which is often used to measure short distances or the size of objects.
In daily life, we can use centimeters to measure the width of books, the size of paper, some parts of the human body and so on. It should be noted that centimeter is a derivative unit based on meter, and there is a conversion relationship with other commonly used length units such as millimeter, meter and kilometer. Specifically, 1 cm is equal to 0.0 1 m and10mm.
Second, the role of centimeters
1, measuring length
Centimeter is used to measure the length, width and height of an object. Such as measuring the size of the book, the length of the cloth, the diagonal of the screen, etc.
Step 2 make clothes
In the process of garment making and cutting, centimeter is a commonly used unit of measurement. Designers and tailors use centimeters to determine the size, length and width of clothes.
3. Medical field
Doctors and nurses use centimeters to measure height, weight, length and depth of wounds, etc. This helps to monitor the health status and treatment progress of patients.
4. Architecture and engineering
In the field of architecture and engineering, centimeters are used to measure the size of buildings, the length of pipes, the distance of cables and so on. This is very important to ensure the accurate installation and operation of buildings and equipment.
5. Painting and art
Artists use centimeters to measure and draw the size, proportion and distance of pictures. It helps to maintain the accuracy and fidelity of the work.
