Revolutions per minute

"RPM" redirects here. For other uses, see RPM (disambiguation).

Revolutions per minute, sometimes called RPM, is a measure of angular frequency. It means the number of times something spins in one minute.

Spins per second	RPM
¼	15
½	30
1	60
2	120
5	300
10	600
25	1500

For example, if a wheel spins one time in one second, it is doing 60 RPM, because there is 60 seconds in one minute.
