1. Homework Statement
What are the units of angular velocity of precession? Ive looked evrywhere and can't find out.

2. Homework Equations

3. The Attempt at a Solution

In my answer to a question, by putting units into the equation i think im getting units as rad^-1 s^-1 but not sure if it should be rads per second.

$$\boldsymbol\omega_p = \frac{Q}{I_s\boldsymbol\omega_s}$$

In which $$I_s$$ is the moment of inertia, $$\boldsymbol\omega_s$$ is the angular velocity of spin about the spin axis, and $$Q$$ is the torque.

Moment of intertia is mass times distance squared.
Angular velocity is radians per second.
Torque is newton-meters, or kilogram meters squared per second squared.

I get the same as you:

$$\frac{1}{rad\times s}$$
