Are G and Rcf the Same?

Relative Centrifugal Force (RCF) or g-force (both are the same, RCF is expressed as units of gravity) is a measurement of the gravitational force that a sample is subject to. ... RCF is the preferred method of measurement as it will remain the same even if you are using a different centrifuge with a different rotor size.

Is RCF equivalent to G?

RCF is expressed in multiples of the standard acceleration due to the earth's gravitational field (times gravity or x g) so don't be surprised if you see RCF and “x g” (g-force) used interchangeably in most centrifugation protocols.

How do you convert RCF to G?

Relative Centrifugal Force (RCF) Formula
  1. Using the G Force Formula. RCF or g force is dependent on the speed of rotation in RPM and the distance of the particles from the center of rotation. ...
  2. G Force Formula. g Force (RCF) = (RPM)2 × 1.118 × 10-5 × r. ...
  3. RPM Formula. RPM = √[RCF/(r × 1.118)] × 1 × 105
