Conversion Examples
Example: Convert 1 inch to centimeters
- Step 1: Identify the conversion factor. Since 1 inch = 2.54 centimeters, multiply inches by 2.54.
- Step 2: Multiply 1 inch by 2.54.
- Step 3: 1 × 2.54 = 2.54 centimeters
1 inch = 2.54 centimeters
This is the fundamental conversion, showing that 1 inch equals exactly 2.54 centimeters by international standard.
Example: Convert 10 inches to centimeters
- Step 1: Use the conversion factor: 1 inch = 2.54 centimeters.
- Step 2: Multiply 10 inches by 2.54.
- Step 3: 10 × 2.54 = 25.4 centimeters
10 inches = 25.4 centimeters
This demonstrates converting a common measurement, often used in product dimensions and technical specifications.
Example: Convert 6 inches to centimeters
- Step 1: Conversion factor: 1 inch = 2.54 centimeters.
- Step 2: 6 inches × 2.54
- Step 3: Result = 15.24 centimeters
6 inches = 15.24 centimeters
This shows converting a common measurement, useful for understanding dimensions in centimeters for international products.
Conversion Formula
The formula to convert inches to centimeters is:
inches × 2.54 = centimeters
Mathematically, you can write this as:
inches × 2.54 centimeters/inch = centimeters
Since 1 inch equals exactly 2.54 centimeters by international standard, multiplying by 2.54 converts inches to centimeters using the standard international conversion factor.
