Conversion Examples
Example: Convert 1 centimeter to inches
- Step 1: Identify the conversion factor. Since 1 centimeter = 0.393701 inches, multiply centimeters by 0.393701.
- Step 2: Multiply 1 centimeter by 0.393701.
- Step 3: 1 × 0.393701 = 0.393701 inches
1 centimeter = 0.393701 inches (approximately)
This is the fundamental conversion, showing that 1 centimeter is slightly less than half an inch.
Example: Convert 10 centimeters to inches
- Step 1: Use the conversion factor: 1 centimeter = 0.393701 inches.
- Step 2: Multiply 10 centimeters by 0.393701.
- Step 3: 10 × 0.393701 = 3.93701 inches
10 centimeters = 3.937 inches (approximately)
This demonstrates converting a common measurement, often used in product dimensions and technical specifications.
Example: Convert 25 centimeters to inches
- Step 1: Conversion factor: 1 centimeter = 0.393701 inches.
- Step 2: 25 centimeters × 0.393701
- Step 3: Result = 9.84252 inches
25 centimeters = 9.843 inches (approximately)
This shows converting a larger measurement, useful for understanding dimensions in inches for international products.
Conversion Formula
The formula to convert centimeters to inches is:
centimeters × 0.393701 = inches
Mathematically, you can write this as:
centimeters × 0.393701 inches/centimeter = inches
Since 1 inch equals exactly 2.54 centimeters, dividing by 2.54 (or multiplying by 0.393701) converts centimeters to inches using the standard international conversion factor.
