Conversion Formula
The formula to convert inches to millimeters is:
millimeters = inches × 25.4
This works because 1 inch equals exactly 25.4 millimeters. The metric system uses millimeters, which are smaller units than inches. So when you multiply the inch value by 25.4, you get the equivalent length in millimeters.
Example calculation:
- Given: 07 inches
- Multiply: 07 × 25.4 = 177.8 mm
- Result: 07 inches = 177.8 millimeters
Conversion Example
- Convert 5 inches to mm:
- Multiply 5 by 25.4
- 5 × 25.4 = 127 mm
- Therefore, 5 inches equals 127 mm.
- Convert 12.5 inches to mm:
- Multiply 12.5 by 25.4
- 12.5 × 25.4 = 317.5 mm
- So, 12.5 inches is 317.5 mm.
- Convert 0.75 inches to mm:
- Multiply 0.75 by 25.4
- 0.75 × 25.4 = 19.05 mm
- Thus, 0.75 inches equals 19.05 mm.
- Convert 20 inches to mm:
- Multiply 20 by 25.4
- 20 × 25.4 = 508 mm
- 20 inches is equal to 508 mm.

Conversion Definitions
Inches: An inch is a unit of length in the imperial and US customary systems, equal to exactly 1/12 of a foot or 2.54 centimeters. It is commonly used in the United States, Canada, and the United Kingdom for measuring smaller distances or objects. Inches are subdivided into fractions or decimals for precision.
Millimeters (mm): The millimeter is a metric unit of length equal to one-thousandth of a meter. It is widely used worldwide in science, engineering, and everyday measurements for small lengths. Millimeters allow for precise measurement because of their small size compared to larger units like centimeters or meters.
Conversion FAQs
Why is the conversion factor from inches to millimeters exactly 25.4?
The value 25.4 mm per inch was internationally agreed upon in 1959 by countries like the US, UK, and others to standardize measurements. It fixes the inch length in metric terms, avoiding confusion caused by older variations that existed. Therefore, every inch equals precisely 25.4 mm now.
Can negative inch values be converted to millimeters?
Yes, negative inch values represent lengths in the opposite direction or below a reference point. The conversion process stays the same, multiplying by 25.4, which results in negative millimeter values. This reflects the same magnitude but on the negative side of the scale.
Is the conversion different if measured for screen size versus physical length?
The conversion formula itself doesn’t change, but screen sizes sometimes use pixels or other units. When converting physical length measurements like rulers or objects, multiply by 25.4. For screen pixels, conversion depends on pixel density and not just inches to mm.
How precise is the conversion from inches to millimeters?
The conversion is exact at 25.4 mm per inch, but rounding can cause slight differences if decimals are cut off. Using more decimal places improves precision. For most practical uses, rounding to four decimal places is enough accuracy.
Are there tools besides manual calculation to convert inches to mm?
Yes, many online converters, smartphone apps, and calculators are available. The conversion tool in this page uses JavaScript to convert values instantly without manual math. Physical measuring tools sometimes show both units too.
