About RPM → RCF Calculator (a gentle organoid spin)
Convert centrifuge speed (RPM) to relative centrifugal force (×g) for a gentle organoid spin, using your rotor radius. Always report ×g, not RPM, for reproducibility. The calculation uses RCF = 1.118×10⁻⁵ · r(cm) · RPM². The stakes: Protocols specify relative centrifugal force (×g), but instruments are set in RPM. Because RCF depends on the square of speed and on rotor radius, the same RPM gives very different g-force on different rotors — get it wrong and you over-pellet, shear, or fail to sediment. For a gentle organoid spin, a typical setting is ~15 ×g. Watch out for: forgetting radius is in cm in the formula; not balancing tubes; copying an RPM from a protocol written for a different rotor. Because the calculation happens entirely client-side, you can use it offline and with confidential data, then cite the stable URL in your methods or teaching notes.

Frequently asked questions
Any tips specific to this calculation?+
For a gentle organoid spin, a typical setting is ~15 ×g. Also watch out for: forgetting radius is in cm in the formula and using rmin instead of rmax.
Is this rpm → rcf calculator (a gentle organoid spin) free to use?+
Yes. It is completely free, needs no sign-up, and runs entirely in your browser — there are no usage limits.
What formula does it use?+
It uses RCF = 1.118×10⁻⁵ · r(cm) · RPM² The full worked example is shown beneath the result so you can verify each step.
What are the most common mistakes here?+
In centrifugation, watch for: copying an RPM from a protocol written for a different rotor; using rmin instead of rmax; forgetting radius is in cm in the formula; not balancing tubes. This tool shows the working so you can catch these before they cost an experiment.
