Conversion Formula
The formula to convert centimeters to inches is: inches = centimeters / 2.54. This works because 2.54 centimeters makes up one inch. When you divide centimeters by 2.54, you are effectively calculating how many inches fit into that length. For example, 10 cm divided by 2.54 equals approximately 3.937 inches.
Conversion Example
- Convert 10 cm to inches:
- Step 1: Write the formula: inches = 10 / 2.54
- Step 2: Divide 10 by 2.54: 10 / 2.54 ≈ 3.937
- Step 3: Result: 10 cm equals approximately 3.937 inches
- Convert 15 cm to inches:
- Step 1: Use the formula: inches = 15 / 2.54
- Step 2: Divide 15 by 2.54: 15 / 2.54 ≈ 5.906
- Step 3: So, 15 cm roughly equals 5.906 inches
- Convert 20 cm to inches:
- Step 1: Apply the formula: inches = 20 / 2.54
- Step 2: Divide 20 by 2.54: 20 / 2.54 ≈ 7.874
- Step 3: Result: 20 cm is approximately 7.874 inches
