What to do next
How it works
Speeds go through meters per second. One mph is exactly 0.44704 m/s, one km/h is 1/3.6 m/s, one foot per second is 0.3048 m/s and one knot is 1,852 m per hour.
Things to keep in mind
For running pace (minutes per mile) the math runs the other way, since pace is time per distance. Divide 60 by the speed in mph to get minutes per mile.
