km/h to mi/h – kilometers per hour to miles per hour – online

Speed ​​in kilometers per hour (km/h, km h-1):

Result in miles per hour (mi/h, mi h-1):

0.00mi/h

mi/h to km/h

How to convert speed from kilometers per hour to mils per hour?

1 km/h ≈ 0.621 mi/h

1 kilometers per hour ≈ 0.621 miles per hour 

 

kilometers per hour (US) = kilometres per hour (UK) = km / h = km h-1 = km • h-1 = kph

Miles per hour = mi / h = mi h-1 = mi • h-1 = mph = m.p.h = MPH

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


υmi/h = υkm/h  x 0.621

υmi/h – speed in miles per hour;

υkm/h – speed in kilometers per hour.

 

For example:

Convert speed 10 km/h to mi/h.

Solution: υmi/h = υkm/h  x 0.621 = 10 x 0.621 = 6.21 mi/h. Answer: 10 km/h = 6.21 mi/h

Convert speed 20 km/h to mi/h.

Solution: υmi/h = υkm/h  x 0.621 = 20 x 0.621 = 12.4 mi/h. Answer: 20 km/h = 12.4 mi/h
