Conversion Formula
The formula to convert inches (in) to millimeters (mm) is:
mm = in × 25.4
This works because one inch is defined as exactly 25.4 millimeters. So, multiplying the number of inches by 25.4 converts the length to millimeters.
Example:
- Convert 0.01 in to mm
- Multiply 0.01 × 25.4 = 0.254 mm
- The result is 0.254 millimeters
Conversion Example
- Convert 2 in to mm:
- Multiply 2 × 25.4 = 50.8
- Result: 50.8 mm
- Convert 5.5 in to mm:
- Multiply 5.5 × 25.4 = 139.7
- Result: 139.7 mm
- Convert 0.75 in to mm:
- Multiply 0.75 × 25.4 = 19.05
- Result: 19.05 mm
- Convert 10 in to mm:
- Multiply 10 × 25.4 = 254
- Result: 254 mm
- Convert 0.125 in to mm:
- Multiply 0.125 × 25.4 = 3.175
- Result: 3.175 mm

Conversion Definitions
In (inch): The inch is a unit of length in the imperial and US customary systems, equal to exactly 2.54 centimeters or 25.4 millimeters. It’s commonly used in the United States for measuring small distances like screen sizes, paper, or fabric length, and is subdivided into smaller units like fractions for precision.
Mm (millimeter): The millimeter is a metric unit of length equal to one thousandth of a meter. It is commonly used around the world for measuring small objects, thickness, and dimensions in engineering and science. Being part of the SI system, it provides a standardized measure for precision.
Conversion FAQs
Why is 1 inch equal to exactly 25.4 millimeters?
In 1959, an international agreement defined the inch as exactly 25.4 millimeters to standardize measurements across different countries. This fixed value replaced earlier approximations, ensuring consistent conversion between the imperial and metric systems.
Can I use the formula mm = in × 25.4 for any value?
Yes, the formula applies to any measurement in inches, whether positive, negative, or fractional. It’s a direct multiplication that converts inches to millimeters accurately, without exceptions.
What happens if I convert negative inches to millimeters?
Negative inch values represent measurements in the opposite direction or below a reference point. Using the same formula, multiplying by 25.4 gives a negative millimeter value, preserving the direction or sign of the measurement.
Is it okay to round the result when converting inches to millimeters?
Rounding depends on the precision needed. For many uses, rounding to two or three decimal places is fine. But for engineering or scientific tasks, keeping more decimal places maintains accuracy.
Does the conversion change if the material expands or shrinks?
The conversion is a mathematical relation and does not account physical changes like expansion or contraction. If the material size changes, the measurement in inches or millimeters should be updated before converting.
