Conversion Formula
The formula to convert inches to millimeters is simple: multiply the number of inches by 25.4. This conversion factor comes from the international agreement where 1 inch equals exactly 25.4 millimeters.
This works because the inch is a unit based on imperial measurement, while millimeters belong to the metric system. Multiplying by 25.4 scales the inch value to the metric equivalent.
Example calculation for 0.07 inch:
- Start with 0.07 inch.
- Multiply by 25.4: 0.07 × 25.4 = 1.778.
- The result is 1.778 millimeters.
Conversion Example
-
Convert 1.5 inch to millimeters:
- Multiply 1.5 by 25.4.
- 1.5 × 25.4 = 38.1 mm.
- Therefore, 1.5 inch equals 38.1 mm.
-
Convert 0.25 inch to millimeters:
- Multiply 0.25 by 25.4.
- 0.25 × 25.4 = 6.35 mm.
- So, 0.25 inch is 6.35 mm.
-
Convert 3 inch to millimeters:
- Multiply 3 by 25.4.
- 3 × 25.4 = 76.2 mm.
- Hence, 3 inches equal 76.2 mm.
-
Convert 0.5 inch to millimeters:
- Multiply 0.5 by 25.4.
- 0.5 × 25.4 = 12.7 mm.
- Thus, 0.5 inch equals 12.7 mm.

Conversion Definitions
Inch: An inch is a unit of length in the imperial and US customary systems, equal to 1/12 of a foot or exactly 25.4 millimeters. It is commonly used in the United States, Canada, and the UK for measuring small distances and dimensions.
Millimeter (mm): A millimeter is a metric unit of length equal to one-thousandth of a meter. It is widely used in most countries for precise measurements in science, engineering, and daily life, representing very small distances accurately.
Conversion FAQs
Why is the conversion factor between inches and millimeters exactly 25.4?
The value 25.4 was internationally agreed upon in 1959 to standardize measurement units between countries using imperial and metric systems. Before this agreement, slight variations existed. The exact value helps ensure consistency in manufacturing, science, and trade across borders.
Can I convert inches to millimeters by approximation instead of using 25.4?
While some approximations like 25 or 25.5 are easier to calculate, they introduce errors. For precision work, using 25.4 is necessary. Approximated conversions might be good for rough estimates but not for engineering or scientific purposes.
Does converting negative inch values to millimeters work the same way?
Yes, negative values represent measurements in the opposite direction or below a reference point. The conversion formula applies the same way, multiplying the negative inch value by 25.4, resulting in a negative millimeter value.
How precise is the conversion from inches to millimeters?
Because 1 inch equals exactly 25.4 millimeters, the conversion is exact mathematically. The precision depends on how many decimal places you keep in the result. For everyday use, four decimals provide sufficient accuracy.
Are there any common mistakes when converting inches to millimeters?
Common errors include forgetting to multiply by 25.4, confusing millimeters with centimeters, or misplacing decimal points. Also, some might round too early, causing loss of accuracy in final measurements.
