# Centrifugal Force and Angular Velocity

 P: 79 1. The problem statement, all variables and given/known data I'm working on a problem in which I have to calculate the centrifugal force. I know the equation and everything, I'm just stuck on what units my angular velocity should have. 2. Relevant equations $$\vec{F_{cen}}=-m\omega\times(\omega \times r')$$ 3. The attempt at a solution I've evaluated the above with angular velocity having units rotations*s^-1. I know that angular velocity should have units rad/s but I'm wondering how one gets units of Newtons when using rad/s as the unit of angular velocity. I've never really understood this, what is so special about radians that you can ignore them when converting units?
