Enter the RPM and the radius into the Calculator. The calculator will evaluate the RCF (relative centrifugal force). 

RCF (relative centrifugal force) Formula

RCF = (RPM)^2 * 1.118 * 10^-5 * r


  • RCF is the RCF (relative centrifugal force) (g-force)
  • RPM is the RPM
  • r (m) is the radius

How to Calculate RCF (relative centrifugal force)?

The following steps outline how to calculate the RCF (relative centrifugal force).

  • First, determine the RPM. 
  • Next, determine the radius. 
  • Next, gather the formula from above = RCF = (RPM)^2 * 1.118 * 10^-5 * r.
  • Finally, calculate the RCF (relative centrifugal force).
  • After inserting the variables and calculating the result, check your answer with the calculator above.
