You will need the conversion factor between angular speed (usually in radians/second) and rpm (revolutions per minute).
We know that one revolution equals 2π radians, and one minute equals 60 seconds, so
60 rpm
= 60 * revolutions/minute
= 60 * (revolutions*2πradians/revolution) / (minute * 60 seconds/ minute )
= (60*2π/60) radians/second
= 2π radians/second
after simplifying the numbers and the units.
