Conversion Formula
The formula to convert kilometers per hour to miles per hour is: mph = km * 0.621371. This works because 1 km/h equals about 0.621371 mph. For example, to convert 72 km/h, multiply 72 by 0.621371: 72 * 0.621371 = 44.74 mph, which is the speed in miles per hour.
Conversion Example
- Suppose you want to convert 50 km/h to mph:
- Multiply 50 by 0.621371.
- 50 * 0.621371 = 31.06855 mph.
- So, 50 km/h equals approximately 31.07 mph.
- Converting 100 km/h:
- 100 * 0.621371 = 62.1371 mph.
- Approximately 62.14 mph.
- Converting 10 km/h:
- 10 * 0.621371 = 6.21371 mph.
- Approximately 6.21 mph.
