RPM ⇄ RCF

Convert centrifuge speed to relative force and back, given the rotor radius.

Force from speed

RCF = k \cdot r \cdot rpm^{2}

\text{RCF}	Relative centrifugal force	×g
k	Lumped constant (1.118 × 10^-5)	1/cm
r	Rotor radius	cm
\text{rpm}	Rotor speed	rpm

Speed from force

rpm = \frac{RCF}{k \cdot r}

\text{rpm}	Rotor speed	rpm
\text{RCF}	Relative centrifugal force	×g
k	Lumped constant (1.118 × 10^-5)	1/cm
r	Rotor radius	cm
