Conversion Formula
The formula to convert inches (in) to millimeters (mm) is:
millimeters = inches × 25.4
This works because one inch is exactly 25.4 millimeters. Multiplying the inch value by 25.4 changes the unit from inches to millimeters.
Example: Convert 008 inches to millimeters step-by-step:
- Start with the value in inches: 0.008 in
- Multiply by 25.4: 0.008 × 25.4 = 0.2032
- Result is 0.2032 mm
Conversion Example
- Convert 2.5 in to mm:
- Multiply 2.5 by 25.4
- 2.5 × 25.4 = 63.5 mm
- Convert 10 in to mm:
- Multiply 10 by 25.4
- 10 × 25.4 = 254 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 12.3 in to mm:
- Multiply 12.3 by 25.4
- 12.3 × 25.4 = 312.42 mm

Conversion Definitions
in (inch): An inch is a unit of length in the imperial and United States customary systems, equal to 1/12 of a foot or exactly 25.4 millimeters. It is commonly used to measure small distances, screen sizes, and dimensions in everyday and technical contexts.
mm (millimeter): A millimeter is a unit of length in the metric system, equal to one thousandth of a meter. It is used widely in science, engineering, and manufacturing for precise measurements, especially when dealing with small dimensions or tolerances.
Conversion FAQs
Why is one inch equal to 25.4 millimeters?
The length of one inch was internationally standardized as exactly 25.4 millimeters in 1959 after agreement between countries using imperial and metric systems. This fixed value ensures consistency in measurement conversions worldwide. It replaced previous definitions based on physical standards.
Can I use the same formula for negative inch values?
Yes, the formula works for negative values too. Negative inches represent lengths in the opposite direction or measurements below a reference point. Multiplying negative inches by 25.4 results in a negative millimeter value, maintaining the correct proportionality.
How accurate is converting inches to millimeters using 25.4?
The conversion factor 25.4 is exact by international agreement. So the conversion is as accurate as the input measurement. Rounding errors may occur if you reduce decimal places, but the base factor is precise and reliable for all practical purposes.
Is it possible to convert fractional inches to millimeters?
Yes, fractional inches can be converted by first expressing the fraction as a decimal number and then multiplying by 25.4. For example, 1/2 inch is 0.5, so 0.5 × 25.4 = 12.7 mm. This method works for any fractional inch value.
What are common applications where inch to millimeter conversions are needed?
This conversion is needed in engineering, manufacturing, construction, and design where parts specified in imperial units must be matched to metric standards or tools. Also, when working with international specifications, converting ensures compatibility across measurement systems.
