Conversion Formula
The formula to convert inches to millimeters is: millimeters = inches × 25.4.
This works because the internationally agreed length of one inch is exactly 25.4 millimeters. So, to find the length in millimeters, you multiply the length in inches by 25.4.
For example, converting 2.28 inches to millimeters:
- Start with 2.28 inches.
- Multiply 2.28 by 25.4:
- 2.28 × 25.4 = 57.912 mm.
- So, 2.28 inches equals 57.912 millimeters.
Conversion Example
- Convert 5 inches to mm:
- Multiply 5 × 25.4.
- 5 × 25.4 = 127 mm.
- Therefore, 5 inches is 127 millimeters.
- Convert 0.75 inches to mm:
- Multiply 0.75 × 25.4.
- 0.75 × 25.4 = 19.05 mm.
- Thus, 0.75 inches equals 19.05 millimeters.
- Convert 12.5 inches to mm:
- Multiply 12.5 × 25.4.
- 12.5 × 25.4 = 317.5 mm.
- So, 12.5 inches is 317.5 millimeters.
- Convert 1.1 inches to mm:
- Multiply 1.1 × 25.4.
- 1.1 × 25.4 = 27.94 mm.
- Hence, 1.1 inches equals 27.94 millimeters.
- Convert 3 inches to mm:
- Multiply 3 × 25.4.
- 3 × 25.4 = 76.2 mm.
- Thus, 3 inches is 76.2 millimeters.

Conversion Definitions
Inches: An inch is a unit of length in the imperial and United States customary systems, defined exactly as 25.4 millimeters. It is commonly used for measuring small distances, screen sizes, and in construction in countries that use imperial units.
Millimeters (mm): A millimeter is a metric unit of length equal to one thousandth of a meter. It is widely used worldwide for precision measurements in engineering, manufacturing, and everyday distances smaller than a centimeter.
Conversion FAQs
Why is one inch exactly 25.4 millimeters?
The inch was standardized internationally in 1959 to be exactly 25.4 millimeters to unify measurements between countries using imperial and metric systems. Before this, inch definitions varied slightly, causing inconsistencies.
Can I convert inches to millimeters by simply multiplying by 2.5?
No, multiplying by 2.5 gives an approximation, but not an accurate conversion. The correct factor is 25.4, so multiplying by 2.5 underestimates the true millimeter value significantly.
Is the conversion the same for fractional inches?
Yes, whether whole numbers or fractions, converting inches to millimeters involves multiplying by 25.4. For fractions, convert to a decimal first before multiplying for accurate results.
Does temperature affect the inch to millimeter conversion?
The conversion itself is fixed and unaffected by temperature. However, materials may expand or contract with temperature changes, changing actual dimensions slightly, but the unit conversion factor stays constant.
How precise is the conversion factor 25.4?
25.4 is exact by international agreement. It defines the inch in metric terms without approximation, meaning conversions using this factor are as precise as the input measurements allow.
