degree per second squared

Angular accelerationexact by definition

The degree per second squared is \(\pi/180\) radians per second squared, about 0.017453 rad/s². It appears in servo and gimbal specifications where rates and accelerations are quoted on a degree scale. The relation is exact by definition, with an irrational decimal value.

Watch out: Convert to rad/s² before using \(\tau = I\alpha\) or any other dynamics relation. Degrees are a display convenience, not a calculation unit.
