What this tool does
Frequency and rotational speed are the same physical quantity expressed for different audiences. A motor turning at 1500 rpm is turning at 25 Hz and 157.08 rad/s; a drive parameter sheet might use any of the three. Radians per second is the form that goes straight into mechanical formulas for power and peripheral speed, which is why converting to it first usually saves a step.
