## How many millimeters are there in an inch?

1 inch contains 25.4 millimeters. Alternatively, 1 millimeter is equivalent to 0.03937 inches.

Millimeters and inches belong to different unit systems. Millimeters are units of distance in the Metric System, and inches are units of distance in the Imperial System.

The symbol used to represent millimeters is mm. On the other hand, the symbol used to represent inches is in or also β³.

Inches can be represented both in decimal form and in fractions, where the denominator is a power of 2. For example, the most common fractions are 1/2, 1/4, 1/8, 1/16, 1/ 32, and 1/64.

## How to convert from millimeters to inches?

To transform from millimeters to inches, we can divide the distance in millimeters by 25.4. Therefore, if we have a distance d in millimeters (mm), we divide it by 25.4 to get the inches.

d_{(in)} = d_{(mm)}/25.4 |

#### Example 1:

Convert 100 millimeters to inches.

We have to divide the number of millimeters by 25.4. Therefore, we have:

*d*_{(in)} = 100/25.4

*d*_{(in)} = 3.937 in

#### Example 2:

How many inches equals 500 millimeters?

To find the number of inches, we divide by 25.4, and we have

*d*_{(in)} = 500/25.4

*d*_{(in)} = 19.685 in

#### Example 3:

Convert 5 millimeters to inches.

If we divide the millimeters by 25.4, we have:

*d*_{(in)} = 5/25.4

*d*_{(in)} = 0.19685 in
