Conversion Formula
The formula for converting inch to millimeter is simple: multiply the value in inches by 25.4. This works because exactly 1 inch equals 25.4 millimeters based on international agreement.
Mathematically, the formula is:
mm = inch × 25.4
For example, converting 0.05 inch:
- Take the inch value: 0.05
- Multiply by 25.4: 0.05 × 25.4 = 1.27
- Result: 1.27 mm
This conversion works because millimeter is smaller unit than inch and the ratio is fixed.
Conversion Example
- Convert 2 inches to mm:
- Multiply 2 by 25.4
- 2 × 25.4 = 50.8 mm
- Therefore, 2 inches is 50.8 millimeters.
- Convert 0.1 inch to mm:
- 0.1 × 25.4 = 2.54 mm
- So 0.1 inch equals 2.54 mm.
- Convert 5.5 inch to mm:
- 5.5 × 25.4 = 139.7 mm
- 5.5 inches equals 139.7 millimeters.
- Convert 12 inch to mm:
- 12 × 25.4 = 304.8 mm
- 12 inches equals 304.8 millimeters.
