uh... converting?

RPM/60         = RPS ( Rev per SECOND )

RPS/360        = degrees per SECOND

               /* note 60*360 = 21600 */

so RPM/21,600 * 1000 (ms per second)   = degrees per mS

   RPM/21.6


restated at:

  to obtain degrees per milliSecond divide RPM by 21.6
 
quick check:
at 8,000 RPM   =  370ms/Degree   (sounds about right. ;-)
