However, if your automobile is idling rough, it will not feel smooth. This article has been viewed 94,484 times. Formula for converting FPM to RPM In order to convert RPM to FPM, you would use the following formula RPM = FPM / (Pi x Diameter) Where P1 = 22/7 or 3.14 and diameter is expressed in ft. You can go to following link for the How to Convert RPM to Feet per Minute RPM, Belt Length, Speed, Animated Diagrams - Inch.
RPM to degree/second In the imperial system, we are given sfm, and the diameter is measured as a decimal of an inch. Note that rounding errors may occur, so always check the results. Weve presumably also observed that engine noise increases as RPM rises. The following equation is used to calculate spindle speed: rpm = sfm diameter 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm 12) (diameter ).
