What is the purpose of pi/30 in the equation. Why can we not just use rpm as unit of measure of angular velocity?

In principle you can, but if you want to use it in formulas together with radians and seconds (e. g. to calculate the kinetic energy of a rotation object) you need a unit conversion.Why can we not just use rpm as unit of measure of angular velocity?

That would be a better way to write your equation:

Revolutions(RPM) * Pi/30 = Angular velocity (rad/s)
