How to convert meters per second to miles per hour
- Take the value in meters per second.
- Use the formula miles per hour = meters per second × 2.236936292.
- For example, 3 m/s is 6.71 mph.
About meters per second and miles per hour
A mile per hour is exactly 0.44704 m/s, so divide meters per second by 0.44704, or multiply by 2.23694, to get mph. For a quick estimate double it and add 10%: 20 m/s gives 44 mph against the exact 44.74.
Physics problems, sports science, wind reports in some countries and spec sheets for drones and fans use m/s. US readers picture speed in mph, so converting puts the number next to familiar driving speeds.
Examples
- 3 m/s (a steady jog, an illustrative pace) is 6.71 mph
- 32.7 m/s (the start of hurricane force, Beaufort 12) is 73.15 mph
- 7,660 m/s (the International Space Station in orbit) is 17,134.93 mph
- 299,792,458 m/s (the speed of light) is 670,616,629.38 mph
