Conversion Examples
Example: Convert 1 kilometer to miles
- Step 1: Identify the conversion factor. Since 1 kilometer = 0.621371 miles, multiply kilometers by 0.621371.
- Step 2: Multiply 1 kilometer by 0.621371.
- Step 3: 1 × 0.621371 = 0.621371 miles
1 kilometer = 0.621371 miles (approximately)
This is the fundamental conversion, showing that 1 kilometer is approximately 0.62 miles, or about 62% of a mile.
Example: Convert 10 kilometers to miles
- Step 1: Use the conversion factor: 1 kilometer = 0.621371 miles.
- Step 2: Multiply 10 kilometers by 0.621371.
- Step 3: 10 × 0.621371 = 6.21371 miles
10 kilometers = 6.214 miles (approximately)
This demonstrates converting a common distance, often used in running races (10K) and road distances.
Example: Convert 100 kilometers to miles
- Step 1: Conversion factor: 1 kilometer = 0.621371 miles.
- Step 2: 100 kilometers × 0.621371
- Step 3: Result = 62.1371 miles
100 kilometers = 62.137 miles (approximately)
This shows converting a longer distance, useful for understanding road trip distances and travel planning in miles.
Conversion Formula
The formula to convert kilometers to miles is:
kilometers × 0.621371 = miles
Mathematically, you can write this as:
kilometers × 0.621371 miles/kilometer = miles
Since 1 mile equals exactly 1.609344 kilometers, dividing by 1.609344 (or multiplying by 0.621371) converts kilometers to miles using the standard international conversion factor.
