How do I convert RPM to RCF for my centrifuge?

Enter your rotor's radius in millimeters and the RPM value; the calculator will output the relative centrifugal force (RCF) in ×g units, accounting for the radius-dependent force applied to your samples.

Why is RCF preferred over RPM when using different centrifuges?

RCF represents the actual force acting on centrifuged items relative to gravity, making it the universal parameter; two centrifuges running at the same RPM can produce different forces if their rotor radii differ.

Can I use this calculator if I only know the RCF value?

Yes, input the desired RCF and your rotor's radius to determine the required RPM settings for your specific centrifuge model.

What does the ×g symbol mean next to RCF values?

The ×g symbol indicates that the relative centrifugal force is expressed as a multiple of gravitational acceleration, showing how many times stronger the force is compared to Earth's gravity.

About this tool

What Centrifuge Calculator does

The Centrifuge Calculator on Omni Calculator converts between relative centrifugal force (RCF) and revolutions per minute (RPM), allowing users to determine appropriate RPM settings for a given RCF or calculate RCF from specific RPMs used in laboratory equipment. The tool outputs the converted value and explains the relationship between the two parameters, noting that RCF corresponds to the force acting on centrifuged items compared to gravitational force (often shown as ×g), while RPM describes rotor speed. It emphasizes that even if two centrifuges have the same RPM, the force depends on rotor radius, making RCF the universal parameter for consistent experimental results. The site provides a brief physics explanation and a link to a centrifugal force calculator for deeper learning.
