Conversion Formula
The formula to convert inches to millimeters is:
millimeters = inches × 25.4
This works because one inch is defined exactly as 25.4 millimeters internationally. Therefore, to get the length in millimeters, you multiply the amount in inches by 25.4.
For example, take 0.118 inches:
- Multiply 0.118 by 25.4
- 0.118 × 25.4 = 2.9972
- Therefore, 0.118 in equals 2.9972 mm
Conversion Example
- Convert 1.5 inches to millimeters:
- Multiply 1.5 × 25.4
- 1.5 × 25.4 = 38.1 mm
- So, 1.5 in equals 38.1 mm
- Convert 0.75 inches to millimeters:
- Multiply 0.75 × 25.4
- 0.75 × 25.4 = 19.05 mm
- So, 0.75 in equals 19.05 mm
- Convert 3.2 inches to millimeters:
- Multiply 3.2 × 25.4
- 3.2 × 25.4 = 81.28 mm
- So, 3.2 in equals 81.28 mm
- Convert 0.01 inches to millimeters:
- Multiply 0.01 × 25.4
- 0.01 × 25.4 = 0.254 mm
- So, 0.01 in equals 0.254 mm

Conversion Definitions
in (inch): The inch is a unit of length in the imperial and US customary systems, equals exactly 2.54 centimeters or 25.4 millimeters. It is commonly used for measuring small lengths in countries like the United States and Canada. An inch is subdivided into 16, 32, or 64 parts for precision.
mm (millimeter): The millimeter is a metric unit of length equal to one thousandth of a meter. This unit is widely used worldwide for precise measurements in engineering, manufacturing, and everyday life. Millimeters provide a smaller scale measure than centimeters or meters, allowing detailed dimensional accuracy.
Conversion FAQs
Why do we multiply inches by 25.4 to get millimeters?
Since one inch is exactly defined as 25.4 millimeters internationally, multiplication by 25.4 converts the length from inches to millimeters. This fixed ratio allows consistent and precise conversion between the two units across all measurements.
Can inches be converted directly to millimeters without using a calculator?
While you can estimate by multiplying by 25, for exact conversions, a calculator or conversion tool helps because 25.4 is not a whole number. Manual calculations might lead to rounding errors if done mentally.
Is 0.118 inches a common measurement in any field?
Yes, 0.118 inches (or around 3 mm) is common in engineering, electronics, and manufacturing, where small dimensions like PCB thickness or component sizes are measured precisely in either inches or millimeters.
Are negative inch values meaningful when converting to millimeters?
Negative inch values simply indicate direction or position relative to a reference point. When converted, negative millimeter values keep that directional meaning. The magnitude conversion remains the same, multiplied by 25.4.
Does the conversion change if the inch value includes fractions?
Fractions of inches can be converted by first converting the fraction to decimal, then multiplying by 25.4. The process is the same, but fractions require converting to decimal form before applying the formula.
