Kilometres per hour to miles per hour
Divide km/h by 1.609344 to get mph. This converts speed; it does not convert kilometres of distance into miles.
Speed ConverterReference for one unit; displayed values may be rounded.
Kilometers per Hour
Use a dot or comma for decimals, without thousands separators.
Miles per Hour
Display rounding does not improve the accuracy of your original measurement. Very large or very small results use scientific notation.
Method and source Unit definitions and conversion referenceDisplayed decimal results are rounded. Converting a speed does not identify the applicable road speed limit.

Kilometers per Hour and Miles per Hour Explained
Kilometers per Hour (km/h)
Kilometers per hour (km/h) measure distance traveled in one hour. One kilometer is 1000 meters; this tool converts speed, not distance or travel time.
Miles per Hour (mph)
Miles per hour (mph) use the international mile of exactly 1609.344 meters. One mph equals exactly 1.609344 km/h; decimal conversion results may be rounded.
