How to convert KPH to MPH

Kilometers per hour (KPH) and miles per hour (MPH) both measure speed, but they use different distance units. Since 1 mile equals 1.60934 kilometers, you can convert between them with a simple calculation.

To convert KPH to MPH, divide by 1.60934:

MPH = KPH ÷ 1.60934

To convert MPH back to KPH, multiply by 1.60934:

KPH = MPH × 1.60934

Example conversions

KPH to MPH speed conversion

Converting 100 KPH to MPH:

100 ÷ 1.60934 = 62.14 MPH

Converting 60 MPH to KPH:

60 × 1.60934 = 96.56 KPH

You can also convert the other direction using the MPH to KPH calculator.

Where is KPH used?

The majority of countries in the world use kilometers per hour as the standard unit for road speed. This includes all of continental Europe, most of Asia, Africa, South America, and Australia. Speed limit signs, car speedometers, and GPS navigation in these countries display speeds in KPH.

The United States, United Kingdom, and a handful of other countries use miles per hour instead. If you're travelling between countries that use different systems — or importing a vehicle — knowing how to convert between KPH and MPH is essential.

FAQs

To convert kilometers per hour to miles per hour, divide the KPH value by 1.60934. For example, 100 KPH ÷ 1.60934 = 62.14 MPH.

100 KPH is equal to approximately 62.14 MPH. This is a common benchmark, as 100 km/h is a standard motorway speed limit in many countries.

120 KPH is equal to approximately 74.56 MPH. Many European motorways have a speed limit of 120 km/h.

130 KPH is equal to approximately 80.78 MPH. France and several other European countries use 130 km/h as their motorway speed limit.

The United States, United Kingdom, and a small number of other countries measure road speed in miles per hour (MPH). Most of the rest of the world uses kilometers per hour (KPH).

100 KPH (about 62 MPH) is a typical highway or motorway speed. It is considered normal road speed in most countries, not particularly fast by modern standards.
