De officiële SI-brochure zegt hierover het volgende: The SI unit of frequency is hertz, the SI unit of angular velocity and angular frequency is radian per second (..). Although it is formally correct to write [both] these units as the reciprocal second, the use of the different names emphasizes the different nature of the quantities concerned. It is especially important to carefully distinguish frequencies from angular frequencies, because by definition their numerical values differ by a factor of 2π. (..) Note also that it is common, although not recommended, to use the term frequency for quantities expressed in rad/s. Because of this, it is recommended that quantities called “frequency”, “angular frequency”, and “angular velocity” always be given explicit units of Hz or rad/s and not $s^{-1}$ ..
