Metres per second to miles per hour
Multiply metres per second by 2.2369 to get miles per hour.
15 m/s = 33.554 mph
How to convert metres per second to miles per hour
The mile per hour is miles travelled per hour, exactly 1.609344 km/h. The metre per second is the SI unit of speed, one metre travelled per second.
Worked example — 15 m/s: 15 × 2.2369 = 33.554 mph.

About metres per second and miles per hour
Metre per second (m/s)
1 m/s = 2.2369 mphDefinition. The SI unit of speed, one metre travelled per second
History and origin
The metre per second is the coherent SI unit of speed, built directly from the base units of length and time. It is the natural choice wherever physics equations are involved.
Current use
Metres per second are used in science and engineering, and to report wind speed in meteorology.

Mile per hour (mph)
1 mph = 0.44704 m/sDefinition. Miles travelled per hour, exactly 1.609344 km/h
History and origin
Miles per hour grew out of the English mile and the hour as roads and railways spread in the nineteenth century. It equals exactly 1.609344 kilometres per hour.
Current use
Miles per hour is the speed unit for road traffic in the United States and United Kingdom, and is common for running pace.

Where people use this
Metres per second: physics, wind speed. Miles per hour: vehicle speed in the US and UK, speed limits, running pace. A 10 m/s wind is about 22.4 mph.
Every value is carried to full double precision; the display is rounded.
Both units are defined in NIST Handbook 44, Appendix C (Tables of Equivalents — international nautical mile); speeds derived from the exact mile, foot and hour.
