> * Everyone who follows the current rules of the SI blindly (as per JadeNB's analysis above) "knows" that a Hz is 1 radian/s. FTFY In any non-brain-dead system, angular frequency (rad/s, degrees/s, rev/s, RPM) has to be accounted for differently than 1/time. This unfortunately won't prevent automated systems from accepting "sin ft" where f is in Hz (incorrect) rather than "sin wt" where w is in rad/s (correct), but there's really no way to handle this automatically.
