centimeter (cm)
A centimeter (cm) is a unit of measurement in the metric system
A centimeter (cm) is a unit of measurement in the metric system. It is equal to one hundredth of a meter. The centimeter is commonly used to measure small distances or lengths, such as the height of objects, the length of a paper, or the size of a small item.
To visualize a centimeter, you can think of it as approximately the width of a small fingernail. It is smaller than a inch, with 1 inch being equivalent to 2.54 centimeters.
In mathematical calculations, centimeters can be converted to other metric units by using conversion factors. For example, 1 centimeter is equal to 0.01 meters, or it can be converted to millimeters by multiplying by 10 (1 cm = 10 mm). Similarly, it can be converted to kilometers by dividing by 100,000 (1 cm = 0.00001 km).
Centimeters are often used in conjunction with other metric units to measure various quantities, such as the length, area, or volume of objects. For instance, the perimeter of a rectangle can be measured in centimeters, where all the sides are summed together to get the total length. Additionally, the volume of a rectangular prism can be measured in cubic centimeters, by multiplying the length, width, and height of the object.
