Conversion Formula
The formula to convert inches to millimeters is:
millimeters = inches × 25.4
This works because the international agreement defined one inch as exactly 25.4 millimeters long. By multiplying the number of inches by this constant, you get the corresponding length in millimeters. The factor 25.4 is fixed, no rounding needed.
For example, converting 0.75 inches:
- Start with the inches: 0.75
- Multiply by 25.4: 0.75 × 25.4 = 19.05
- Result: 19.05 millimeters
Conversion Example
- Example: Convert 2 inches to mm
- Take 2 inches
- Multiply by 25.4: 2 × 25.4 = 50.8
- Result: 50.8 millimeters
- Example: Convert 5.5 inches to mm
- Start with 5.5 inches
- Calculate 5.5 × 25.4 = 139.7
- The final value is 139.7 millimeters
- Example: Convert 0.1 inches to mm
- Begin with 0.1 inches
- Multiply 0.1 × 25.4 = 2.54
- Answer: 2.54 millimeters
- Example: Convert 10 inches to mm
- Use 10 inches
- Calculation: 10 × 25.4 = 254
- Result is 254 millimeters

Conversion Definitions
Inches: An inch is a unit of length in the imperial and US customary systems, defined as exactly 25.4 millimeters. It is subdivided into fractions, commonly halves, quarters, eighths, and sixteenths. Inches are used in the United States, Canada, and UK for measuring height, length, and width.
Millimeters (mm): 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 measurements. One millimeter is about the thickness of a credit card or a grain of rice.
Conversion FAQs
Why is one inch exactly 25.4 millimeters and not some other value?
The length of one inch was internationally standardized in 1959 to exactly 25.4 millimeters to unify measurements between imperial and metric systems. Before that, slight variations existed. This exact value simplifies engineering and international trade by providing a fixed conversion factor.
Can I use the conversion factor 25 mm per inch for quick estimates?
While 25 mm per inch is close, it’s not exact. Using 25.4 mm per inch ensures precise calculations. For rough estimates, 25 mm might be okay, but for engineering or technical work, always use 25.4 to avoid errors.
What happens when I convert large measurements from inches to millimeters?
When converting large numbers, multiplying by 25.4 scales the measurement accurately. The result will be larger in millimeters since millimeters are smaller units. Watch out for rounding errors if your calculator or software limits decimal places.
Is there a difference between US customary inches and international inches?
Since 1959, the US customary inch and international inch have been defined identically as 25.4 millimeters. Before, small differences existed but now no practical difference exists, so conversions to millimeters use the same factor.
How precise is the conversion result when using decimals?
The conversion is exact to the last decimal when using 25.4 as the factor, but rounding to decimal places limits precision. For example, 0.75 inches equals exactly 19.05 mm, but if rounded too early or too much, small errors may appear in the result.
