Centrifuge RCF to RPM Calculator

Convert between relative centrifugal force (RCF/g-force) and revolutions per minute (RPM) for any rotor radius used in laboratory centrifugation.

Relative Centrifugal Force (x g)

Rotor Radius (mm)

Conversion Direction

Formula

RCF = 1.118 x 10^-5 x r x RPM^2; RPM = sqrt(RCF / (1.118 x 10^-5 x r)); where r = rotor radius in mm
