Conversion kilometers per hour to miles per hour, km/h to mph.

The conversion factor is 0.621371192; so 1 kilometer per hour = 0.621371192 miles per hour. In other words, the value in km/h divide by 1.6093440006147 to get a value in mph. The calculator answers the questions: 40 km/h is how many mph? or change km/h to mph. Convert km/h to mph.

Conversion result:

100 km/h = 62.13712 mph

100 kilometers per hour are 62.13712 miles per hour.
