Conversion Formula
The formula to convert inches to millimeters is:
millimeters = inches × 25.4
Each inch contains exactly 25.4 millimeters because the metric system defines the inch as exactly 25.4 mm. So, multiplying the number of inches by 25.4 changes the measurement unit. For example, to convert 050 inches:
- Start with 050 inches (which is 0.50 inches).
- Multiply 0.50 by 25.4.
- 0.50 × 25.4 = 12.7 mm.
This shows 0.50 inches equals 12.7 millimeters, although the question was 050 (which is parsed as 50), so:
- 50 × 25.4 = 1270 mm.
Conversion Example
- Example 1: Convert 12 inches to mm
- Multiply 12 by 25.4.
- 12 × 25.4 = 304.8 mm.
- Example 2: Convert 3.5 inches to mm
