Conversion Formula
The formula to convert inches (in) into millimeters (mm) is:
mm = in × 25.4
This formula works because one inch is defined as exactly 25.4 millimeters. Multiplying the inch value by 25.4 gives the equivalent length in millimeters.
Example:
- Convert 5 in to mm
- 5 × 25.4 = 127 mm
This means 5 inches equals 127 millimeters.
Conversion Example
- Convert 3.5 in to mm:
- Multiply 3.5 by 25.4
- 3.5 × 25.4 = 88.9 mm
- Result: 3.5 in equals 88.9 mm
- Convert 12 in to mm:
- 12 × 25.4 = 304.8 mm
- So, 12 inches is 304.8 millimeters
- Convert 0.75 in to mm:
- 0.75 × 25.4 = 19.05 mm
- Thus, 0.75 inch equals 19.05 mm
- Convert 20 in to mm:
- 20 × 25.4 = 508 mm
- Therefore, 20 inches equals 508 millimeters

Conversion Definitions
in (inch): An inch is a unit of length in the imperial and US customary systems. It equals 1/12 of a foot or exactly 25.4 millimeters. Inches are commonly used in the United States, Canada, and the UK for measuring smaller distances, such as screen sizes, height, and fabric.
mm (millimeter): A millimeter is a metric unit of length equal to one thousandth of a meter. It is used worldwide for precise measurements in science, engineering, and everyday applications. One millimeter equals 0.03937 inches, making it much smaller than an inch.
Conversion FAQs
Can negative inch values be converted to millimeters?
Yes, negative inch values represent measurements in the opposite direction or below a reference point. The conversion formula still applies by multiplying the negative inch value by 25.4, which gives a negative millimeter value accordingly.
Is the conversion factor 25.4 exact or approximate?
The factor 25.4 is exact by international agreement. One inch is defined as exactly 25.4 millimeters with no rounding. This ensures consistent and accurate conversions between imperial and metric measurements.
Why does the input field accepts decimal inches?
Since many measurements in inches include fractions or decimals (like 3.75 in), the tool accepts decimal inputs to provide precise conversions. This allows users to convert any inch value, whole or fractional, into millimeters accurately.
Does this conversion apply for linear measurements only?
Yes, the formula applies strictly for linear lengths. For areas, volumes or other measurements, different conversion factors or formulas are needed because the units represent different dimensions.
Can this method convert inches to other metric units?
While this tool converts inches directly to millimeters, converting to centimeters or meters involves additional steps by dividing millimeters by 10 or 1000 respectively after conversion.
