Conversion Formula
The formula to convert inches to millimeters is simple multiplication:
millimeters = inches × 25.4
Since one inch is exactly 25.4 millimeters, multiplying any length in inches by 25.4 converts it to millimeters. This works because the two units measure the same distance but in different scales.
Example:
- Given: 9.5 inches
- Multiply: 9.5 × 25.4
- Calculate: 9.5 × 25.4 = 241.3 mm
Thus, 9.5 inches equals 241.3 millimeters.
Conversion Example
- Convert 3 inches to mm:
- Multiply 3 × 25.4
- Result: 76.2 mm
- So, 3 inches is 76.2 millimeters.
- Convert 12.7 inches to mm:
- Multiply 12.7 × 25.4
- Result: 322.58 mm
- Therefore, 12.7 inches equals 322.58 mm.
- Convert 0.5 inches to mm:
- Multiply 0.5 × 25.4
- Result: 12.7 mm
- This means half an inch is 12.7 millimeters.
- Convert 20 inches to mm:
- Multiply 20 × 25.4
- Result: 508 mm
- So, 20 inches corresponds to 508 millimeters.
