How do I calculate centrifugal force from RPM?

Convert RPM to angular speed with pi, then use omega squared r.

Is centrifugal force the same as centripetal force?

They have the same magnitude for the same circular motion, but centripetal force is inward in an inertial frame while centrifugal force is an outward rotating-frame description.

What is g-force or RCF?

It is the circular acceleration divided by standard gravity, useful for centrifuge and rotating-equipment comparisons.

Centrifugal force and circular motion

English intent combines classroom circular motion with engineering and centrifuge g-force checks. The calculator reports the outward rotating-frame force and the equivalent inward centripetal-force magnitude.

F = m ω^{2} r

m is mass, omega angular speed and r radius to the center of mass.

F = \frac{m v ^{2}}{r}

v is tangential speed at the selected radius.

R C F = \frac{ω ^{2} r}{g}

Relative centrifugal force compares acceleration with standard gravity.

Safety boundary

Not a strength check

This calculator does not verify rotor strength, balance, bearings, bolts, fatigue, containment or laboratory safety limits.
