Convert Miles per Hour to Kilometres per Hour


If you want to know how fast something is moving in kilometres per hour (km/h) when you only know its speed in miles per hour (mph), you can use a simple calculator or formula to convert it.

Why Convert?

  • Miles per hour (mph) is a unit used mostly in the US and UK.
  • Kilometres per hour (km/h) is used in most other countries.
  • If you want to understand speed or distance in km/h, you need to convert mph to km/h.

How to Convert

  • 1 mile = 1.60934 kilometres.
  • So, to convert miles per hour to kilometres per hour, multiply the speed in mph by 1.60934.

Formula

Speed in km/h=Speed in mph×1.60934

Example:

If a tractor is moving at 10 mph, then:

10×1.60934=16.0934 km/h

So, the tractor is moving about 16.1 km/h.

Using the Calculator

  • Enter the speed in miles per hour.
  • The calculator multiplies by 1.60934.
  • It shows the speed in kilometres per hour.

This helps farmers understand speeds in local units or compare speeds if they see information in mph or km/h.
