Conversion Formula
The formula to convert inches to millimeters is:
millimeters = inches × 25.4
This works because one inch exactly equals 25.4 millimeters by international agreement. Multiplying the length in inches by 25.4 translates the measurement into millimeters. For instance, 0.75 inches × 25.4 = 19.05 millimeters.
Step-by-step example:
- Start with 0.75 inches.
- Multiply 0.75 by 25.4.
- Calculation: 0.75 × 25.4 = 19.05.
- Result is 19.05 millimeters.
Conversion Example
- Convert 1.5 inches to mm:
- Multiply 1.5 by 25.4.
- 1.5 × 25.4 = 38.1.
- So, 1.5 inches equals 38.1 mm.
- Convert 2.25 inches to mm:
- Multiply 2.25 by 25.4.
- 2.25 × 25.4 = 57.15.
- Therefore, 2.25 inches is 57.15 mm.
- Convert 0.1 inches to mm:
- Multiply 0.1 by 25.4.
- 0.1 × 25.4 = 2.54.
- Thus, 0.1 inch equals 2.54 mm.
- Convert 3 inches to mm:
- Multiply 3 by 25.4.
- 3 × 25.4 = 76.2.
- So, 3 inches equals 76.2 mm.

Conversion Definitions
Inches: An inch is a unit of length in the imperial and US customary systems, equal to 1/12 of a foot or 2.54 centimeters. It is used in many countries for measuring small distances, especially in construction, manufacturing, and everyday objects like screens or paper sizes.
Millimeters (mm): A millimeter is a metric unit of length, one thousandth of a meter. It is commonly used worldwide for precision measurements in engineering, manufacturing, and science. Millimeters provide a smaller scale than centimeters, making it easier to measure fine dimensions accurately.
Conversion FAQs
Why is the inch defined as exactly 25.4 millimeters?
The inch was internationally standardized to equal 25.4 millimeters in 1959 to unify measurement systems between countries like the US and those using metric. Before this, slight variations existed, causing confusion. Fixing it at 25.4 mm ensures consistency in manufacturing and trade.
Can I convert inches to millimeters by dividing instead of multiplying?
No, converting inches to millimeters requires multiplying by 25.4 because millimeters are smaller units than inches. Dividing would give incorrect smaller values. Multiplication scales the inch quantity up to millimeters accurately.
Why does the conversion use 25.4 and not a rounded number like 25?
25.4 mm is the exact length defined for one inch internationally. Using 25 instead would cause errors in precision and accumulate rounding mistakes in measurements. The decimal value 25.4 ensures exactness in calculations and manufacturing.
How do decimals affect converting inches to millimeters?
Decimals allow precise conversion of fractional inches into millimeters. Since one inch equals 25.4 mm, even small decimal parts like 0.75 inches can be converted accurately by multiplying. Without decimals, conversions would be limited to whole numbers, less accurate.
Is the conversion from inches to millimeters reversible?
Yes, to convert millimeters back to inches, divide the millimeter value by 25.4. This reverses the multiplication step and returns the original inches value. Both conversions keep measurement consistent in different units.
