km/h = mph × 1.60934

Knot → Mile per Hour

mph = kn × 1.15078

Mile per Hour → Knot

kn = mph × 0.868976

Formula

m/s = mph × 0.44704

One mile per hour equals 0.44704 meters per second. Since 1 mile = 1609.344 meters, dividing by 3600 seconds gives 0.44704 m/s per mph. Used in physics, engineering, and vehicle speed specifications.
