RPM to RCF Calculator

Convert centrifuge speed between RPM and relative centrifugal force (×g) using rotor radius.

CORE EQUATIONRCF = 1.118×10⁻⁵ × r × RPM²
WHAT IT DOES

From formula to a bench-ready decision.

Translate between RPM and ×g for a specified rotor radius.

Tossora Lab keeps units, intermediate values, and practical preparation checks visible so a mathematically correct answer is easier to translate into an experimental workflow.

BUILT-IN CHECKS

What Tossora Lab checks.

  • Uses rotor radius in centimeters.
  • Supports RPM-to-RCF and RCF-to-RPM conversion.
  • Keeps radius visible because RPM alone does not define centrifugal force.
BENCH NOTES

Before you use the result.

  • Use the actual radius for the rotor and tube position in your setup.
  • When a protocol specifies ×g, match ×g rather than copying RPM from another centrifuge.

Research use only. Verify critical calculations, reagent specifications, route or instrument limits, and procedures against your approved protocol and institutional requirements.
