Conversion Formula
The formula to convert miles (mi) to kilometers (km) is:
km = mi × 1.60934
This works because one mile is equal to exactly 1.60934 kilometers. Multiplying the number of miles by this factor gives the corresponding distance in kilometers. The factor comes from the international agreement that defines the length of a mile relative to the metric system.
Example calculation for 14.9 mi:
- Multiply 14.9 by 1.60934
- 14.9 × 1.60934 = 23.975966
- Rounded, it becomes 23.9759 km

Conversion Definitions
mi (mile): A mile is a unit of length commonly used in the United States and the UK, equal to 5,280 feet or 1,609.34 meters. It originated from Roman times and remains in use for road distances, measuring travel or land in non-metric systems.
km (kilometer): A kilometer is a metric unit of length equal to 1,000 meters. It is widely used worldwide for measuring distances, especially in countries using the metric system. One kilometer equals about 0.621 miles.
Conversion FAQs
Why is the conversion factor exactly 1.60934?
This factor comes from the international agreement defining a mile as 1,609.344 meters, rounded to 1.60934 kilometers for convenience. It ensures consistency across measurements between imperial and metric units, allowing precise distance conversions.
Can I use the same conversion factor for converting kilometers to miles?
No, when converting kilometers to miles, you use the inverse factor: 1 km equals approximately 0.621371 miles. Using the mile-to-km factor directly would give incorrect results.
Why do some conversions show slightly different results?
Variations occur because some sources round the conversion factor differently or use truncated decimals. Small differences happen if you round intermediate steps instead of final result.
Is negative distance meaningful when converting mi to km?
Negative distances represent direction or displacement rather than length. The conversion formula works the same, multiplying by 1.60934, but negative values usually indicate reverse direction or debts in measurement.
Are miles and kilometers both used for measuring speed?
Yes, miles per hour (mph) and kilometers per hour (km/h) are common speed units. To convert speeds, multiply mph by 1.60934 to get km/h, paralleling the distance conversion.
