Convert miles per hour [mph] to kilometers per hour [km/h] and vice-versa

Online converter

Convert any value from / to kilometers per hour [km/h] to miles per hour [mph]. Fill one of the following fields, values will be converted and updated automatically.

Formulas

• Convert kilometers per hour to miles per hour (km/h => mph)
• Convert miles per hour to kilometers per hour (mph => km/h)

Explanation

1 mile = 1.609344 km (exactly)

By convention, 1 mile exactly equal to 1.609344 kilometers, it becomes trivial to deduce the following formula:

$$ v_{(km/h)} = 1.609344 \times v_{(mph)} $$

and vice-versa:

$$ v_{(mph)} = \dfrac{v_{(km/h)}}{1.609344} $$
