Miles per hour (mph) to Meters per second (m/s) Conversion
Miles per hour
Miles per hour (mph) is the unit of speed used in road transport in the United States, United Kingdom, and a small number of other countries. One mile per hour equals approximately 1.60934 km/h or 0.44704 m/s. Speed limits on US interstate highways are commonly 65–75 mph, while the UK national speed limit is 70 mph.
Meters per second
Metres per second (m/s) is the SI coherent derived unit of speed, the preferred unit for speed in physics, engineering, and scientific literature worldwide because it integrates directly into SI equations. The speed of sound at 20 °C is approximately 343 m/s, human sprinting speed approaches 12 m/s, and the speed of light is exactly 299,792,458 m/s.
