The angular frequency ω is given by ω = 2π/T . The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time.

ω = 2 * π * f , where f is the frequency. As we can see, it is denoted by the same letter. Additionally, the unit of angular frequency is rad/s , precisely the same as for the angular velocity.
