About Meters per Second and Kilometers per Hour
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. The kilometer per hour is the road speed unit of most of the world — exactly 1/3.6 of a meter per second. Speed limits, car speedometers, and rail and cycling speeds use it outside the US and UK. One Meters per Second equals 3.599999997 Kilometers per Hour (1 mps = 3.599999997 kph). Meters per Second to Kilometers per Hour conversion comes up most often in physics calculations and in wind speed reporting in metric countries, typically when figures need restating for road speed limits outside the US and UK.
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.
