About Miles per Hour and Meters per Second
The mile per hour is exactly 1.609344 kilometers per hour, the road speed unit of the US and UK. Tennis serves, baseball pitches, and hurricane winds are also quoted in mph. The meter per second is the SI derived unit of speed. Physics, wind reporting in many countries, and sprint analysis use it directly, and every other speed unit converts through it. One Miles per Hour equals 0.44704 Meters per Second (1 mph = 0.44704 mps). Miles per Hour to Meters per Second conversion comes up most often in US and UK speed limits and in ball sports speeds (pitches, serves), typically when figures need restating for physics calculations.
Precision and Rounding: Most speed factors are exact because they derive from exact length and time definitions (1 mph = 1.609344 km/h precisely); Mach is the exception, since the speed of sound varies with temperature and altitude — the figure used here is 343 m/s, the sea-level value at 20 °C. One decimal place covers driving and running; aviation and ballistics carry more.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
Worked Example
15 Miles per Hour equals 6.7056 Meters per Second.
