How do you convert radians per second to rpm?

Only if its metres / sec in a circular path, then you would need the radius to work out its revs per second, then multiply by (2 * pi) to get radians / sec.>Example 10 m/s at 10 m...

the tangential velocity is equal to the angular velocity multiplied by the radius the tangential velocity is equal to the angular velocity multiplied by the radius

You cannot.Radians per second is a measure of angular speed whereas degrees are an angular measure.

1 rotation/1 min * 1 min/60s * (2*Pi radian/1 rotation)

1 rpm = 2pi radians per minute = 2pi/60 radians per second = pi/30 radians per second..or:Divide rpm by 60 = revs / second, then multiply by (2 * pi).so:(rpm / 60) * (2 * pi) = radians per...
