About RPM → RCF Calculator (pelleting nanoparticles)
Convert centrifuge speed (RPM) to relative centrifugal force (×g) for pelleting nanoparticles, using your rotor radius. Always report ×g, not RPM, for reproducibility. The calculation uses RCF = 1.118×10⁻⁵ · r(cm) · RPM². Why accuracy here pays off: 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 pelleting nanoparticles, a typical setting is ~30000 ×g. Mistakes that trip people up: not balancing tubes; copying an RPM from a protocol written for a different rotor; using rmin instead of rmax. No account, no upload, no tracking of your inputs — the result is generated on your machine, which makes it reproducible, private and citable in published work.

Frequently asked questions
Any tips specific to this calculation?+
For pelleting nanoparticles, a typical setting is ~30000 ×g. Also watch out for: not balancing tubes and forgetting radius is in cm in the formula.
Is this rpm → rcf calculator (pelleting nanoparticles) 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.
Does my data leave my device?+
No. All computation happens locally in your browser. Nothing you enter — sequences, concentrations or measurements — is uploaded to any server, so it is safe for confidential work.
Can I cite this tool?+
Yes — use the “Cite this tool” snippet on the page. Many users link these calculators from methods sections, lab SOPs and teaching materials.
