#### 3 Ways to Calculate RPM - wikiHow

You can relate the RPM of an object turned by wind to the actual wind speed by first finding the circumference traveled by one of the object's arms in one rotation. You then convert this distance to either miles or kilometers and multiply that by the RPM to determine how much distance the object rotated through in 1 minute.

#### Learn Cnc Speeds & Feeds - with rpm & feedrate calculator

Next we can consider machining some aluminum stock. A SFM, on a benchtop mill or router, of 500 would be a safe starting point. Using the same end mill as in the previous calculation you get an RPM of 7,640 which, as you would expect, is double the previous result. Again when you calculate the feedrate it is double the previous result at 61 in/min.
