From "[URL Wikipedia - Earth's rotation[/URL]
The angular speed of Earth's rotation in inertial space is (7.2921150 ± 0.0000001) ×10−5 radians per SI second (mean solar second).[11] Multiplying by (180°/π radians)×(86,400 seconds/mean solar day) yields 360.9856°/mean solar day, indicating that Earth rotates more than 360° relative to the fixed stars in one solar day.
If I want to know the mean angular velocity for any other planet of the Solar system and for the Sun itself, should I take the rotation period for each object and do the inverse in order to get the angular velocity in rad/s?
Here there is a list of rotation periods for the above objects:
