Conversion Definitions
mph: Miles per hour (mph) measures how many miles a vehicle travels in one hour, used mainly in the US and UK. It indicates speed based on the imperial unit mile, and helps quantify how quickly something moves over a given time.
kph: Kilometers per hour (kph) measures how many kilometers a vehicle covers in one hour, used worldwide except in the US and UK. It provides a metric way to express speed, based on the kilometer, a unit of length in the metric system.
Conversion FAQs
Why is the conversion factor from mph to kph 1.60934?
