Meters per Second to MPH Converter
Convert meters per second to miles per hour — multiply by 2.2369. Results update as you type; exact factors shown.
One meter per second is 2.2369 miles per hour — see the exact factor, not a rounded rule of thumb.
How the meters per second to mph converter works
Speeds convert through meters per second. 1 km/h is 1000/3600 m/s; 1 mph is 1609.344/3600 m/s; a knot is one nautical mile (1,852 m) per hour. Mach is shown against the standard sea-level speed of sound of 340.29 m/s and varies with altitude and temperature.
The US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.
