Home / Lab Calculators / RCF ↔ RPM
Enter rotor radius and either RPM or RCF; leave the unknown empty. Radius is the distance from the rotor center to the sample position in centimeters.
Formula: RCF = 1.118×10⁻⁵ · r(cm) · RPM². Minimum, average and maximum radii give different g-force in the same rotor; use the radius specified for your tube position.
