How to Calculate Machine RPM | eHow

Video of the Day. Convert surface speed to feet per minute. To convert from meters per second, multiply by 196.85. For instance, if the surface speed is 2 m/s: 2 * 196.85 = 393.7. Multiply your answer by 4. 393.7 * 4 = 1,574.8. Convert your cutter's diameter to feet. For instance, if your cutter measures 6in across: 6 / 12 = 0.5 ft.
