MPH to KPH Calculator

What is the difference between KM and MPH?

Kilometers (KM) is a measure of distance. Kilometer is also a way of measuring speed, where normally it is measured against time such as kilometers per hour (km/h or kph).

MPH means miles per hour, another measurement of speed. Sometimes you may also see it written as KMH, which also has the same meaning. Both miles per hour (mph) and kilometers per hour (kph) are common measurements of speed for road vehicles such as cars, trucks and motorbikes.

To encourage road safety, speed limits are assigned to roads and highways to reduce the casualties caused by driving at high speeds.

How to convert between km/h and mph?

First we need to find the difference between the measurements of 1 mile and 1 kilometer. When comparing distances, 1 mile = 1.60934 kilometer.

To convert miles per hour to kilometers per hour (mph to kmh), we need to multiply the miles per hour value by 1.60934 to get the result in kilometers per hour.

We can also reverse this to convert kilometers per hour to miles per hour. This time we will need to divide the amount in kilometers by 1.60934 to get the result in miles per hour. As you can see, it's easy to switch between km/h and mph as needed.

Example Conversion of KMH and MPH

Converting miles per hour (MPH) to kilometers per hour (km/h) is a simple division problem. If a car is going 60 miles per hour (mph) then you can do the following:

60 x 1.60934 = 96.56 kph

The result of this conversion is 96.56 km/h (or KPH), which we can then round to 97 kilometers per hour. If you want to see more conversions like this then check out the MPH to KM Conversion Chart at the bottom of this page.
