Formula & Background

The relationship between RPM (revolutions per minute) and RCF (relative centrifugal force) is defined by the following formula:

RCF = 1.118 × 10-5 × r × (RPM)2
  • RCF is the relative centrifugal force (g-force).
  • r is the rotational radius in centimeters (cm). Note: Our calculator accepts millimeters (mm) and handles the conversion for you.
  • RPM is the speed of rotation in revolutions per minute.
