About converting Mile per Hour to Meter per Sec

Converting Mile per Hour to Meter per Sec is a common speed conversion. One mile per hour (mph) equals 0.44704 meter per sec (m/s). Miles per hour are used for speed limits and weather in the US and UK.

This conversion is commonly needed for sailing and marine navigation, physics and engineering calculations, driving and speed limit compliance. Meters per second is the SI unit for speed, used in physics and engineering.

To put mile per hour in perspective: a US highway speed limit (65–75 mph). In meter per sec, common references include speed of sound at sea level (343 m/s).

Did you know?

Even though the UK uses miles for road speed limits, it uses kilometers for most other measurements — a split that dates back to an incomplete 1965 metrication effort.

Mile per Hour (mph)
  • a bicycle ride (about 15 mph)
  • a US highway speed limit (65–75 mph)
