RCF to RPM Converter
How to convert RPM and RCF
- Type the rotor radius in cm, from the center to the bottom of the tube.
- Choose which way to convert, and type the RPM or the RCF (× g).
- 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.
