Converting kilometers per hour (km/h) to miles per hour (mph) is a common unit conversion, especially when comparing speeds in countries that use the metric system (km/h) versus the imperial system (mph). Here is how to do it:
Key Conversion Factor:
1. 1 kilometer per hour (km/h) ≈ 0.621371 miles per hour (mph). - This means:
1km/h=0.621371mph
Conversion Formula:
To convert kilometers per hour to miles per hour, multiply the speed in km/h by 0.621371:
Speed in mph=Speed in km/h×0.621371
Example Conversion:
If a car is traveling at 100 km/h, the speed in mph is:
100km/h×0.621371=62.1371mph
Key Points:
1 km/h ≈ 0.621371 mph: This is the exact conversion factor.
1 mph ≈ 1.60934 km/h: This is the inverse conversion factor.
Applications: This conversion is commonly used in travel, automotive speed limits, and athletic performance metrics.
Quick Reference:
- 50 km/h ≈ 31.07 mph
- 80 km/h ≈ 49.71 mph
- 100 km/h ≈ 62.14 mph
- 120 km/h ≈ 74.56 mph
Notes:
- For quick mental calculations, you can approximate 1km/h≈0.6mph. For example:
100km/h×0.6=60mph
This approximation is close enough for everyday use.
