Converting centimeters (cm) to inches (in) is straightforward. The key to the conversion is the number 2.54.
By international definition, one inch is equal to exactly 2.54 centimeters. This precise relationship gives us a simple formula for converting any measurement.
The simplest and most accurate way to convert centimeters to inches is to divide your length value by 2.54.
Inches = Centimeters / 2.54So, if you have a measurement in centimeters, just take that number and get the result in inches when it is divided by 2.54.
Example: To convert 20 cm to inches:
20 cm / 2.54 = 7.874 inches
You can also convert by multiplying. Because 1 inch is equal to 2.54 centimeters, it means that 1 centimeter is equal to 0.3937008... inches (which is simply 1 / 2.54).
Inches = Centimeters × 0.3937While both formulas work, using the division method (dividing by 2.54) is generally recommended because 2.54 is the exact, official conversion value.

A centimeter (cm) is a unit of length in the metric system.
It is equal to one hundredth of a meter (0.01 m). The plural form is centimeters.
One of the most crucial facts about the centimeter is its relationship with the inch.
There are exactly 2.54 centimeters in one inch.
This precise conversion factor is essential for global trade, engineering, and daily life. It enables easy and accurate translation between the metric system (used by most of the world) and the imperial system (still used in countries such as the United States).
Gaining a clear understanding of this cm to inch conversion is essential for various tasks, including purchasing clothing and international manufacturing.
The centimeter is a cornerstone of the Centimeter-Gram-Second (CGS) system of units.
This system was an essential precursor to the modern International System of Units (SI).
In the CGS system, the centimeter was the base unit of length, the gram the base unit of mass, and the second the base unit of time.
While less common today, it's still widely used in specific fields of physics, such as astrophysics, for calculating other vital units like force and energy.
To understand how big a centimeter is, it helps to use common items as a useful mental benchmark. This is great for estimating its length without a ruler.
A centimeter is approximately the same width as:
