Convert Miles per hour to Metres per second
1 mile per hour is 0.44704 m/s. One mile per hour is exactly 0.44704 metres per second.
One mile per hour is 0.44704 metres per second. To convert miles per hour to metres per second, multiply by 0.44704; to go the other way, divide by 0.44704 or multiply by 2.2369363. The factor is exact rather than rounded: it follows from NIST Special Publication 811. Exactly 0.44704 m/s, because a mile is exactly 1,609.344 metres.
