What is the conversion factor between inches and centimeters?
A conversion factor is used to change the units of a measured quantity without changing its value. It represents the ratio (or fraction) that expresses the relationship between two different units. A conversion factor is always equal to 1.
The relationship between inches and centimeters is 2.54, such as:
Following the formula above, we can see that there are 2.54 centimeters for every inch, and for every centimeter, there are 12.54 inches (0.393701 in).
To convert from inches to centimeters, we turn our formula into a conversion factor that is equal to 1.
Both these fractions are equal to 1. The numerator and the denominator are equivalent, they are just expressed in different units.
Because we are converting from inch to centimeter, we will use the first fraction: 2.54 cm1 in so that inches are canceled out. We then multiply the value in inches by this fraction to get the result in centimeters (see example).
Note that in is in the denominator (bottom) of the conversion factor. This is important, you always want to have the unit you are converting from at the bottom and the unit you are converting to in the numerator (top).
You will find below how to use this ratio to convert from in to cm. Just remember for now that the conversion factor for converting from inches to centimeters is:
Which is bigger, an inch or a centimeter?
When it comes to measurements, there can be some confusion over which is bigger, a inch or an centimeter. To find out which one is larger, we must first convert one unit to the other and then compare them.
- 1 in = 2.54 cm
- 2.54 centimeters is bigger than 1 centimeter.
- 1 inch is, therefore, bigger than 1 centimeter.
- To be more specific, a centimeter is 2.54 times smaller than an inch.

How to convert inches to centimeters?
Multiplying any value by 1 will get you the same value back. You can do that one time or multiple times.
For example:
- 77 x 1 = 77
- 557 x 1 x 1 x 1 = 557
Multiplying by 1 is the first step in any unit conversion problem. The second step is to replace the number 1 with the conversion factor that is also equal to 1.
For example, if we want to convert 10 inches into centimeters we multiply 10 in by the conversion factor of 2.54 cm1 in
By replacing the number 1 with the conversion factor, inches are canceled out and we get the result in centimeters. And since the conversion factor is equal to 1, multiplying it with the original value won't change its magnitude and will only change its unit.
Based on this, we can conclude that 10 inches are equal to 25.4 centimeters.
Remember:
- When converting from inches to centimeters, we use 2.54 cm1 in as a conversion factor.
