Conversion Formula
The formula to convert mph to km is: km = mph * 1.6093. This works because miles and kilometers are units of distance, and multiplying by 1.6093 adjusts the value to the metric system. For example, converting 10 mph:
- 10 mph * 1.6093 = 16.093 km
- This means traveling at 10 miles per hour is equivalent to moving at 16.093 kilometers per hour.
Conversion Example
- Convert 5 mph to km:
- Multiply 5 by 1.6093
- 5 * 1.6093 = 8.0465 km
- So, 5 mph equals 8.0465 km.
- Convert 2 mph to km:
- 2 * 1.6093 = 3.2186 km
- Therefore, 2 mph is 3.2186 km.
- Convert 20 mph to km:
- 20 * 1.6093 = 32.186 km
- Thus, 20 mph equals 32.186 km.
- Convert 0.5 mph to km:
- 0.5 * 1.6093 = 0.8047 km
- So, half a mile per hour is 0.8047 km.
- Convert 15 mph to km:
- 15 * 1.6093 = 24.1395 km
- Meaning, 15 mph equals 24.1395 km.

Conversion Definitions
mph
Miles per hour (mph) is a unit of speed measuring the number of miles traveled in one hour, used primarily in the United States and UK for speed limits and travel speeds, representing how far a vehicle moves in a given time in miles.
km
Kilometer (km) is a metric unit of length equal to 1000 meters, used worldwide for measuring distances, particularly in countries that employ the metric system, providing a standard measurement for longer distances.
Conversion FAQs
Why does mph convert to km by multiplying with 1.6093?
This factor is based on the conversion rate between miles and kilometers; since 1 mile equals 1.6093 kilometers, multiplying mph by this number directly gives the speed in km/h, ensuring an accurate transition between units.
Can I use rounded numbers for quick estimation?
Yes, for rough calculations, you can use 1.6 as the conversion factor. For example, 1 mph ≈ 1.6 km/h, which provides a close estimate, but for precise measurements, stick with 1.6093.
Is the conversion factor the same for all speeds?
Yes, the 1.6093 multiplier applies universally, regardless of the speed value, because it is a constant based on the distance units, making it valid for converting any mph value to km/h.
What is the difference between km/h and km in conversion?
km/h indicates a speed (distance over time), whereas km measures a static length. The conversion discussed is about speed units, converting miles per hour into kilometers per hour.
How accurate is the conversion for very high speeds?
The 1.6093 factor remains accurate at high speeds, but measurement errors can occur due to instrument precision. The conversion factor itself is exact, but real-world measurements may have slight deviations.
