There is a built-in frequency unit "rpm" which I am assuming stands for "revolutions per minute".
But in MathCAD Prime 3.0 I am finding that 1 rpm is equal to 6.238/min or 0.105/sec.
But my understanding of revolutions per minute is that it shoud be equal to 1/min or 0.017/sec.
To put it differently, my feeling is that 60 rpm should be equal to 1/sec or 1 Hz but that is not what MCP 3.0 is calculating.
Am I missing something?
