Centrifuge RCF and RPM Converter
Convert in both directions with the entered rotor radius kept visible.
What would you like to do next?
Keep rotor radius in the conversion
Enter rotor radius in centimetres and an RPM to calculate relative centrifugal force using the displayed equation. A second target-RCF input performs the reverse square-root conversion with the same radius. Reporting both directions on one screen helps prevent an RPM copied from one rotor from being treated as a universal force.
Use the radius required by the method and equipment
Rotor geometry and the definition of radius can differ between protocols and instruments. The calculator does not check tube, rotor or centrifuge limits and does not choose a run condition. Confirm manufacturer documentation, balance, containment and the approved method before operating equipment.
Frequently asked questions
Why does radius matter?
Relative centrifugal force changes in direct proportion to rotor radius at a fixed RPM.
What radius unit is expected?
Enter centimetres for the displayed formula constant.
Does the result check equipment limits?
No. Verify RPM and RCF against the rotor and centrifuge documentation.
