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.

Yes, you would need to divide by 60 to convert from rev/min to radians/second. This is because radians is a unit of angle measure while rev/min is a unit of rotational speed. To convert from rev/min to radians/second, you would need to multiply by the conversion factor of (2*pi radians/1 rev) and then divide by 60 seconds/1 minute. This would give you the final answer of approximately 49.95 radians/second. It is important to consider the units when converting between different types of measurements.
