Formula
miles per hour = meters per second × 2.23693629e+0
Speed is distance per unit time. 1 m/s = 3.6 km/h. 1 mph = 1.609344 km/h. 1 knot = 1.852 km/h (one nautical mile per hour).
About Meters per second and Miles per hour
Meters per second (m/s): The SI derived unit for speed (distance / time); 1 m/s = 3.6 km/h. Common uses: Physics and engineering calculations, wind speed in meteorology, sports analytics (sprint speeds), and any context where speed feeds into other equations.
Miles per hour (mph): Derived from the mile (1,609.344 m exactly) and the hour; conventional speed unit in the US, UK, and a handful of other countries. Common uses: US road speed limits, US sports speeds (baseball pitches in mph), UK road signs, and most US vehicle dashboards.
How the conversion works
Speed is distance per unit time. 1 m/s = 3.6 km/h. 1 mph = 1.609344 km/h. 1 knot = 1.852 km/h (one nautical mile per hour).
The exact relationship is miles per hour = meters per second × 2.23693629e+0, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between meters per second and miles per hour comes up wherever speed measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
