Speed in kilometers per hour (kph):
Result in miles per hour (mph):
How to convert speed from kilometers per hour to mils per hour?
1 kph ≈ 0.621 mph
1 kilometers per hour ≈ 0.621 miles per hour
kilometers per hour (US) = kilometres per hour (UK) = kph = km / h = km h-1 = km • h-1
Miles per hour = mph = m.p.h = MPH = mi / h = mi h-1 = mi • h-1
Speed in miles per hour is equal to speed in kilometers per hour multiply by 0.621.
Formulas:
miles per hour = kilometers per hour x 0.621 371 192
υmph = υkph x 0.621
υmph – speed in miles per hour;
υkph – speed in kilometers per hour.
For example:
Convert speed 10 kph to mph.
Solution: υmph = υkph x 0.621 = 10 x 0.621 = 6.21 mph. Answer: 10 kph = 6.21 mph
Convert speed 20 kph to mph.
Solution: υmph = υkph x 0.621 = 20 x 0.621 = 12.4 mph. Answer: 20 kph = 12.4 mph
