Mile per hour to Meter per second Formula & Unit Definitions
One mile per hour equals exactly 0.44704 meters per second (1 mph = 0.44704 m/s). To convert miles per hour to meters per second, multiply by 0.44704. Conversely, to convert meters per second to miles per hour, divide by 0.44704 (or multiply by 2.236936).
Quick Estimation: One mph is just under half a meter per second. To mentally estimate m/s from mph, divide by 2 and subtract roughly 10%. For example, 60 mph is about 26.8 m/s.
