The International System of Units (SI) unit of frequency is the hertz (Hz):
1 r/min = 1/60 Hz
* This is often used for measuring waves, such as radio and sound.
The SI unit of angular speed is the radian per second:
1 r/min = 2π rad/min = 2π/60 rad/s = 0.10471976 rad/s
However, there is no movement to use either of these units of measure (which are primarily used in physics) to replace revolutions per minute when measuring the rotational speed of machinery.k

Revolutions per minute are just units of measurement for angular velocity. Divide the number of revolutions by the number of minutes.

buy a stop watch and count the number of revolutions in a minute. (By the way - are you serious?)

You already got your answer so you do not need Einstein.
