Angle velocity is the expression of angular velocity in radians per unit time. It is calculated with the equation θ/t = πgω/πkr.
The definition of Angular Velocity used by these calculators may not be what you are used to. It is a distance over a time where that distance is curved. Not an angle over time as is commonly used. For more information please read Angular Velocity and Angular Momentum by Miles Mathis. To understand the transforms used to convert angular velocity into an angle velocity, please read my Spin Velocity paper.
