Conversion Formula

The formula used to convert millimeters (mm) to inches (in) is:

inches = millimeters ÷ 25.4

This works because one inch is exactly defined as 25.4 millimeters. So, to find how many inches a length in millimeters represents, divide the mm value by 25.4.

For example, converting 50.8 mm to inches step by step:

• Start with 50.8 mm.
• Divide 50.8 by 25.4.
• 50.8 ÷ 25.4 = 2.
• Thus, 50.8 mm equals 2 inches.

Conversion Example

• Example 1: Convert 100 mm to inches
  • Divide 100 by 25.4.
  • 100 ÷ 25.4 = 3.937.
  • So, 100 mm is approximately 3.937 inches.
• Example 2: Convert 12.7 mm to inches
  • Divide 12.7 by 25.4.
  • 12.7 ÷ 25.4 = 0.5.
  • Therefore, 12.7 mm equals 0.5 inches.
• Example 3: Convert 33 mm to inches
  • Divide 33 by 25.4.
  • 33 ÷ 25.4 ≈ 1.299.
  • Hence, 33 mm is about 1.299 inches.
• Example 4: Convert 75 mm to inches
  • Divide 75 by 25.4.
  • 75 ÷ 25.4 ≈ 2.953.
  • So, 75 mm converts to approximately 2.953 inches.
