Speed conversions are used in driving, sports, aviation, weather, and physics. The most common need is converting between kilometers per hour and miles per hour when traveling between countries.

Understanding Kilometers per Hour and Knots

Most of the world posts speed limits in kilometers per hour, while the US and UK use miles per hour. Meters per second is the scientific standard, and knots (nautical miles per hour) are used in aviation and maritime navigation. A car at 100 km/h is traveling about 62 mph — a conversion worth knowing for any international driver.

How accurate is this conversion?

Speed conversions are exact because they derive directly from exact length and time definitions. Since 1 mile = 1.609344 kilometers exactly, all speed conversions between these units are precise.

All conversion factors on ClearUnits are based on internationally recognised standards (the International System of Units, SI, and official definitions). Factors are reviewed for accuracy and the calculator uses full-precision values, rounding only the displayed result.
