kph to mph

How to convert speed from mph to kph?

1 mph ≈ 1.609 kph

1 miles per hour ≈ 1.609 kilometers 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 kilometers per hour is equal to speed in miles per hour multiply by 1.609.

Formulas:

kilometers per hour = miles per hour x 1.609 344

υ_kph = υ_mph  x 1.609

υ_kph – speed in kilometers per hour;

υ_mph – speed in miles per hour.

For example:

Convert speed 10 mph to kph.

Solution: υ_kph = υ_mph  x 1.609 = 10 x 1.609 = 14.67 kph. Answer: 10 mph = 14.67 kph

Convert speed 20 mph to kph.

Solution:υ_kph = υ_mph  x 1.609 = 20 x 1.609 = 29.3 kph. Answer: 20 mph = 29.3 kph
