How to calculate Centrifugal Force (RFC)? 

Relative Centrifugal Force (RCF) is a measure of the centrifugal force generated by a spinning rotor in a centrifuge. It is used to separate and purify substances based on their size and density, and is important in many fields including medicine, biology, and chemistry.

The formula for calculating RCF is RCF = (RPM)² × 1.118 × 10⁻⁵ × r, where RPM is the revolutions per minute of the rotor, and r is the rotational radius in centimeters. This formula is used to convert RPM to RCF, and is an important tool for determining the appropriate centrifuge settings for a given experiment.

The G force formula is simply another name for the RCF formula. G force and RCF are interchangeable terms that refer to the same concept: the relative centrifugal force generated by a spinning rotor.

The RPM formula is used to calculate the RPM required to generate a specific RCF. The formula is RPM = √[RCF/(r × 1.118)] × 1 × 10⁵, where RCF is the desired relative centrifugal force, and r is the rotational radius in centimeters.

The variable r in the RCF and RPM formulas stands for the rotational radius of the centrifuge rotor. This is the distance between the center of rotation and the outer edge of the rotor, and it plays a crucial role in determining the magnitude of the centrifugal force generated by the rotor.

RCF = Relative Centrifugal Force
RPM = Rotational Speed (revolutions per minute)
r = Centrifugal radius in mm = distance from centre of the turning axis to the bottom of the centrifuge
