Miles ↔ Kilometers Converter
Miles and Kilometers — Quick Conversion
Use this converter to quickly switch between miles (mi) and kilometers (km). It's useful for travel planning, fitness tracking, vehicle distance conversions, and any situation where you need to convert between imperial and metric distance units. The ability to switch between these units allows users to better understand distances while traveling or exercising.
The converter automatically converts your input by first converting to a base unit (meters) and then converting to the target unit, ensuring accuracy and consistent calculations across unit types. This two-step process helps eliminate potential errors and provides you with reliable outcomes every time.
How the Conversion Works
We convert your input distance to meters (the base unit), then from meters to the requested target unit. This two-step approach reduces rounding differences and keeps conversion factors simple. By understanding how the conversion works, you can perform calculations manually if needed.
Result = (Value × From Unit Factor in meters) / To Unit Factor in metersConversion factors used:
- 1 mile = 1609.34 meters
- 1 kilometer = 1000 meters
Examples of Conversion
10 miles to kilometers
10 mi × 1609.34 = 16093.4 m → 16093.4 / 1000 = 16.0934 km
5 kilometers to miles
5 km × 1000 = 5000 m → 5000 / 1609.34 = 3.106856 mi
FAQ — Miles ↔ Kilometers
Is the conversion exact?
Conversion factors are standardized (1 mi = 1609.34 m, 1 km = 1000 m). We round results for readability but retain precision in calculations. Use the PDF export for an exact snapshot of inputs and results. This ensures that you have a reliable reference for your calculations.
Can I convert negative distances?
Negative distances are not supported in this calculator. Enter zero or positive values to get meaningful conversion results. If you're measuring something that cannot be negative in real life, it's best to stick to those parameters.
How do I download the result?
