To convert millimeters to inches, divide the number of millimeters by 25.4 to get the equivalent length in inches.
What is millimeter?
The millimeter (mm) is a unit of length in the metric system, used globally for measurements. One millimeter equals one thousandth of a meter (0.001 m).
The metric system is based on powers of ten and converts between different units, such as millimeters, centimeters, meters, and kilometers.
What is an Inch?
An inch (in) is a unit of length in the imperial system, used for measurements in the United States and some other countries.
In the metric system, one inch is defined as exactly 25.4 millimeters. This definition provides an accurate conversion factor between inches and millimeters.
Conversion Formula
To convert millimeters (mm) to inches (in), you can use the following formula:
Inches = Millimeters ÷ 25.4
This formula divides the millimeters (mm) values by 25.4 to get the length in inches.
Example: 75mm ÷ 25.4 = 2.9527 in
What is Practical Uses?
Generally, in the following sectors, these units are mostly used:
- Engineering: Some countries use the metric system, while other countries use the imperial system. Therefore, it is important for companies to convert units in both the systems. Because, manufacturing parts may need to fit in another country using a different measurement system.
- Daily Use: Unit conversion is beneficial for understanding the dimensions of objects, materials or a any home project.
- Science and Medicine: Professionals in this field need to convert between different units. Because they use scientific instruments that can be made with millimeters or inches.
