RPM ↔ RCF calculator

Convert centrifuge RPM to relative centrifugal force (×g) and back, from the rotor radius.

Calculated in this browser. Nothing is sent anywhere.

RCF = 1.118×10⁻⁵ · r(cm) · rpm². Radius 0.1–100 cm measured to the tube bottom at full swing-out, RPM 1–1,000,000, RCF up to 10,000,000×g. Rotor specs differ — check the manual for the actual radius.

How to use

  1. Enter the rotor radius in cm.
  2. Fill RPM or RCF.
  3. Read the other value.
