Conversion Formula
The formula to convert kilometers per hour to miles per hour is: mph = km * 0.621371. This works because 1 kilometer equals approximately 0.621371 miles. By multiplying km by this factor, we shift the measurement from metric to imperial units, giving us mph.
For example, if you have 100 km/h:
- Multiply 100 km by 0.621371
- 100 * 0.621371 = 62.1371
- This means 100 km/h equals roughly 62.14 mph.
Conversion Example
- Convert 200 km to mph:
- Multiply 200 km by 0.621371
- 200 * 0.621371 = 124.2742
- The speed in miles per hour is approximately 124.27 mph.
- Convert 50 km to mph:
- 50 * 0.621371 = 31.06855
- So, 50 km/h is about 31.07 mph.
- Convert 10 km to mph:
- 10 * 0.621371 = 6.21371
- 10 km/h equals roughly 6.21 mph.
- Convert 300 km to mph:
- 300 * 0.621371 = 186.4113
- Thus, 300 km/h is approximately 186.41 mph.
