A brisk walking pace is about 1.4 m/s. An Olympic 100 m sprinter peaks above 12 m/s. In miles per hour, that gives you: 1 m/s = 2.23694 mph, 10 m/s = 22.3694 mph, 100 m/s = 223.694 mph.
The meter per second (m/s) is the SI derived unit of speed. It is the preferred unit in physics, engineering, and any scientific context. The speed of light in vacuum is exactly 299,792,458 m/s, which is how the meter itself is now defined.
The mile per hour (mph) is the customary speed unit in the United States and the United Kingdom. The conversion 1 mph = 0.44704 m/s is exact, derived from 1 mile = 1609.344 m. A useful mental shortcut: multiply mph by 1.6 to get a close km/h estimate.
