Meters Per Second to Miles Per Hour
Meters per second is the SI unit of speed, used in physics and to describe wind speed in weather forecasts. Miles per hour is the standard speed unit on road signs and speedometers in the US and UK. 1 m/s equals ≈2.23694 mph, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to speed, measured here against speed's base unit (m/s) — every other speed unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
mph = m/s × ≈2.23694
m/s = mph × 0.44704
Worked example: 5 m/s × ≈2.23694 = ≈11.1847 mph.
