Conversion Formula

The basic formula to convert inches to millimeters is:

millimeters = inches × 25.4

This formula works because by definition, 1 inch = 25.4 millimeters exactly. Multiplying any inch value by 25.4 converts that length into millimeters.

For example, converting 0.07 inch:

• Start with 0.07 inch
• Multiply by 25.4: 0.07 × 25.4 = 1.778
• Result is 1.778 mm

Conversion Example

• Convert 2.5 inches to mm:
  • Multiply 2.5 × 25.4 = 63.5 mm
  • So 2.5 inches equals 63.5 millimeters
• Convert 0.5 inch to mm:
  • Multiply 0.5 × 25.4 = 12.7 mm
  • 0.5 inch is 12.7 millimeters
• Convert 10 inches to mm:
  • Multiply 10 × 25.4 = 254 mm
  • 10 inches equals 254 millimeters
• Convert 0.125 inch to mm:
  • Multiply 0.125 × 25.4 = 3.175 mm
  • 0.125 inch equals 3.175 millimeters

Conversion Definitions

Inch: An inch is a unit of length in the Imperial and US customary systems, commonly used in the United States, Canada, and the UK. It equals exactly 2.54 centimeters or 25.4 millimeters, and is subdivided into smaller fractions used in many industries and everyday measurements.

Millimeter: 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 manufacturing. There are 1000 millimeters in a meter, making it a convenient unit for small length measurements.

Conversion FAQs

Why is 1 inch equal to 25.4 millimeters?

The inch was redefined internationally in 1959 as exactly 25.4 millimeters to unify measurements across countries using Imperial and metric systems. Before that, inch lengths varied slightly between regions. Having a fixed value allows consistent conversions.

Can I convert inches to millimeters by dividing?

No, converting inches to millimeters requires multiplying by 25.4, not dividing. Dividing would give incorrect results because millimeters are smaller units. Multiplying scales the inch value to the larger count of millimeters within the same length.

Are negative inch values valid in conversion?

Yes, negative inch values can be converted to millimeters mathematically by multiplying them by 25.4, resulting in negative millimeter values. This might be useful in contexts like displacement or coordinate positions where negative length measurements occur.

How precise is the conversion from inch to millimeter?

Since 1 inch exactly equals 25.4 mm by definition, the conversion itself is precise. However, rounding may occur depending on decimal places used. For most practical purposes, four decimal places provide sufficient accuracy.

Does the conversion factor change for different types of inches?

Although there are historical variations like the survey inch, the international inch used today is always 25.4 mm exactly. Some specialized fields might use alternate definitions, but for general and engineering use, 25.4 mm per inch applies universally.
