Converting km/h to mph: A Quick Guide
Understanding how to convert kilometers per hour (km/h) to miles per hour (mph) is essential, especially when traveling between countries using different speed units. While km/h is the standard unit of speed in most countries, mph is commonly used in the United States and the United Kingdom.
The Conversion Formula
The conversion between km/h and mph is straightforward. To convert km/h to mph, multiply the speed by 0.621371. Conversely, to convert mph to km/h, multiply by 1.60934.
Formula:
Speed (mph) = Speed (km/h) × 0.621371
Example Conversion
For instance, if you're driving at 100 km/h and want to know the equivalent speed in mph:
100 km/h × 0.621371 = 62.1371 mph
So, 100 km/h is approximately equal to 62.14 mph.
