💨 Speed Converter
Enter a speed in any unit and see it converted to every other unit at once — m/s, km/h, mph, knots, ft/s and Mach.
Mach here uses the standard sea-level speed of sound (340.29 m/s at 15°C in dry air) as a fixed reference — it is an approximation, since the true speed of sound varies with altitude, temperature and air density.
