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

Variables:

- 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.
