Convertion formula
miles per hour to kilometres per hour (mph to kph)
The speed S(kph) in kilometres per hour is equal to the speed S(mph) in miles per hour times 1.609344:
S(kph) = S(mph) × 1.609344
Example of conversion
Convert 30 mph to kilometres per hour:
S(kph) = 30 mph × 1.609344 = 48.280 kph
