Calculation History

Centimeters (cm) and inches (in) are two of the most commonly used units of length measurement. While the metric system uses centimeters as its primary unit of length, the imperial system uses inches. The conversion between these two units is essential for many applications, including engineering, construction, and science.

Concepts

What is a centimeter?

A centimeter is a unit of length in the International System of Units (SI), which is the current form of the metric system. It is defined as 1/100 meters. A centimeter is based on the SI unit meter and is equal to one hundredth of a meter. The prefix “centi” indicates that it is one hundredth of a meter.

What is an inch?

An inch is a unit of length in the imperial and US customary systems of measurement. It was defined to be equivalent to exactly 25.4 millimeters in 1959. There are 12 inches in a foot and 36 inches in a yard.

Why convert cm to inches?

Converting centimeters to inches is necessary when working with different measurement systems or when dealing with measurements from different countries. For example, if you are working on a project that requires both metric and imperial measurements, you will need to convert between centimeters and inches.

Formulae

The formula for converting centimeters to inches is straightforward. One inch is equal to 2.54 centimeters. Therefore, to convert centimeters to inches, you need to divide the number of centimeters by 2.54.

Conversion Formula

1 inch = 2.54 cm

Example

To convert 10 centimeters to inches, you would do the following: inches = 10 cm / 2.54 = 3.937007874015748

Benefits

Converting between units of measurement can be beneficial in many ways:
