How to convert rev/min to rad/s when doing calculations involving rotations? We know what 1 rev (revolution) = 2`pi` rad (radians), 1 min (minute) = 60 s (seconds) and therefore if there's x rev/min, we get the following:

x rev/min = (x rev/min) * (2`pi` rad / 1rev) * (1min / 60s) = `pi`x/30  rad/s
