Millimeters vs Inches: A Basic Overview

Millimeters (mm) are metric units of length, used primarily to measure small objects or distances. They are defined as one-thousandth of a meter (m), the base unit of length in the International System of Units (SI).

Inches (in), on the other hand, are imperial units of length commonly used in the United States and some other countries. They are defined as 1/12th of a foot (ft), another imperial unit of length.

Conversion: 25.4 mm Equals 1 Inch

The conversion between millimeters and inches is a fundamental relationship in measurement systems. By definition, 25.4 millimeters is equal to 1 inch. This conversion factor is derived from the fact that there are 25.4 mm in an inch.

Conversion Formula and Calculation

To convert millimeters to inches, you can use the following formula:

25.4 mm VS 1 Inch: Understanding the Conversion

inches = millimeters ÷ 25.4

Key Points

For example, to convert 100 mm to inches, we would calculate:

inches = 100 mm ÷ 25.4 = 3.937 inches

Conversion Chart

Here is a table summarizing the conversion between millimeters and inches for various values:

Millimeters (mm) Inches (in)
10 0.394
25 0.984
50 1.969
100 3.937
200 7.874
