The Angular Frequency calculator computes an angular frequency (ω) based on an input period of rotation, T.

INSTRUCTIONS:  Choose the preferred units and enter the following:

  • T: This is the period of rotation.

Angular Frequency(ω): The calculator computes the Angular Frequency (ω) in radians per second.  However, this can be automatically converted to other angular frequency units (e.g. degrees per minute) via the pull-down menu.

The Math

The angular frequency is the number of increments of `2*pi` radians (`2*pi` radians is one complete rotation) divided by the period of the rotation, outputting simply rotations per unit time.

Since frequency is the inverse of period, `f = 1/T` [1], and angular frequency is a multiple of frequency: `omega = 2*pi*f`, we can substitute for frequency, f and get the angular frequency as a function of period:

`omega = (2*pi) /T`
