Convert 477 rev/min to Radians: Answer & Explanation

[brncsfns5621]

If I was given 477 rev/min and I need to convert to radians, I would use:

477rev (2*pi radians/1 rev) = 2997.07 radians

Question is do I need to divide by 60 to get radians/second instead of minutes?

rev/minute does not convert to radians. It converts to units of angle/time. So it converts to radians/minute (which you correctly show as $2\pi *477 = 2997 rad/min$ or 3000 rad/min. using 3 significant figures) or radians/sec. It is then a simple matter to convert your answer in radians/min to radians/sec.
