About this tool
The mile is the imperial unit of distance used for road signs, speed limits and everyday distances in the United States and the United Kingdom. It descends from the Roman “mille passus”, or a thousand paces.
The kilometer is the metric unit of distance used for the same purpose almost everywhere else in the world, including on road signs, in sports timing, and in scientific measurement.
This conversion is useful when reading a distance, pace or speed limit quoted in miles and needing the kilometer equivalent — common when traveling, following international sports results, or comparing vehicle specifications.
