Conversion Formula
The formula to convert inches to millimeters is:
millimeters = inches × 25.4
This works because the international agreement sets one inch exactly equal to 25.4 millimeters. Multiplying the inch value by 25.4 scales it up to the metric system’s smaller unit.
Example calculation for 1.1 inches:
- Start with 1.1 inches.
- Multiply 1.1 by 25.4 (the number of millimeters per inch).
- 1.1 × 25.4 = 27.94 millimeters.
Conversion Example
- Convert 2.5 in to mm:
- Multiply 2.5 by 25.4.
- 2.5 × 25.4 = 63.5 mm.
- Convert 0.75 in to mm:
- Multiply 0.75 by 25.4.
- 0.75 × 25.4 = 19.05 mm.
- Convert 5 in to mm:
- Multiply 5 by 25.4.
- 5 × 25.4 = 127 mm.
- Convert 10.2 in to mm:
- Multiply 10.2 by 25.4.
- 10.2 × 25.4 = 259.08 mm.

Conversion Definitions
in (inch): An inch is a unit of length in the imperial and US customary systems, defined as exactly 25.4 millimeters. It is commonly used in the United States and Canada for measuring small distances, such as screen sizes, paper dimensions, and construction materials.
mm (millimeter): A millimeter is a metric unit of length equal to one-thousandth of a meter. It is widely used worldwide in science, engineering, and everyday measurements for its precision in expressing small distances or thicknesses, like in manufacturing or printing.
Conversion FAQs
Why is 1 inch equal to 25.4 mm?
Because in 1959, the inch was internationally defined as exactly 25.4 millimeters to unify measurements between imperial and metric systems. This fixed value eliminates confusion when converting between units, providing consistency in engineering, manufacturing, and trade.
Can I convert inches to millimeters by estimation?
You can estimate by multiplying inches by 25, but this will be less accurate. Using 25.4 as the multiplier ensures exact conversion. Estimations might be fine for rough measurements but not for technical or engineering purposes.
Is the conversion factor ever different than 25.4?
No, the conversion factor is fixed internationally at 25.4 millimeters per inch. Historical variations existed, but today this is the standard used everywhere for accuracy and consistency.
How does temperature affect inch to millimeter conversions?
Temperature can cause materials to expand or contract, slightly changing actual length, but the unit conversion factor remains constant. For precise measurements, consider thermal expansion separately, not the conversion itself.
Why use millimeters instead of inches in technical drawings?
Millimeters provide smaller units which allow for more precise measurements and easier calculations in the metric system. Many countries and industries prefer millimeters because they integrate better with other metric units.
