RCF to RPM Converter

How to convert RPM and RCF

  1. Type the rotor radius in cm, from the center to the bottom of the tube.
  2. Choose which way to convert, and type the RPM or the RCF (× g).
  3. The answer appears as you type.

Frequently asked questions

What is the formula?

RCF = 1.118 × 10⁻⁵ × radius (cm) × RPM².

Where do I find the rotor radius?

In the rotor manual or on the rotor itself. Use the maximum radius to match the RCF quoted in most protocols.

Can I see what the force does?

The Centrifuge Simulator spins a 3D rotor at the RPM and radius you set and shows particles pelleting faster as the × g rises.
