Conversion Examples
Example: Convert 39,370 inches to kilometers
- Step 1: Identify the conversion factor. Since 1 inch = 0.0000254 kilometers, multiply inches by 0.0000254.
- Step 2: Multiply 39,370 inches by 0.0000254.
- Step 3: 39,370 × 0.0000254 = 1 kilometer
39,370 inches = 1 kilometer
This is the fundamental conversion, showing that 39,370 inches equals 1 kilometer by international standard.
Example: Convert 100,000 inches to kilometers
- Step 1: Use the conversion factor: 1 inch = 0.0000254 kilometers.
- Step 2: Multiply 100,000 inches by 0.0000254.
- Step 3: 100,000 × 0.0000254 = 2.54 kilometers
100,000 inches = 2.54 kilometers
This demonstrates converting a common measurement, often used in scientific and engineering contexts.
Example: Convert 1,000,000 inches to kilometers
- Step 1: Conversion factor: 1 inch = 0.0000254 kilometers.
- Step 2: 1,000,000 inches × 0.0000254
- Step 3: Result = 25.4 kilometers
1,000,000 inches = 25.4 kilometers
This shows converting a very large measurement, useful for understanding large scale dimensions in kilometers.
Conversion Formula
The formula to convert inches to kilometers is:
inches × 0.0000254 = kilometers
Mathematically, you can write this as:
inches × 0.0000254 kilometers/inch = kilometers
Since 1 inch equals exactly 2.54 centimeters and 1 kilometer equals 100,000 centimeters, 1 inch equals 2.54/100,000 = 0.0000254 kilometers, which is the standard international conversion factor.
