How to use the centrifuge relative centrifugal force calculator
Convert a centrifuge rotor speed and radius into relative centrifugal force (×g). Enter rotor speed, rotor radius in the fields above; the relative centrifugal force, tangential speed are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “RCF calculator”, “centrifuge g force”, “rpm to g”, “calculate centrifuge relative centrifugal force”, “find relative centrifugal force”.
Formula
Variables
- rpm — Rotor speed (rpm)
- rc — Rotor radius (cm)
Worked example
With rotor speed = 3000 rpm, rotor radius = 10 cm, the calculator gives relative centrifugal force ≈ 1,006.42 × g; tangential speed ≈ 31.41593 m/s.
Frequently asked questions
What is the centrifuge relative centrifugal force calculator used for?
Convert a centrifuge rotor speed and radius into relative centrifugal force (×g). It helps with questions such as “RCF calculator”, “centrifuge g force”, “rpm to g”.
What is the formula for the centrifuge relative centrifugal force calculation?
Relative centrifugal force (× g) = (2 × π × rpm / 60)^2 × (rc / 100) / GRAV. Tangential speed (m/s) = 2 × π × rpm / 60 × rc / 100. Here rpm is rotor speed (rpm), rc is rotor radius (cm).
What inputs do I need for the centrifuge relative centrifugal force calculator?
You need rotor speed in rpm, rotor radius in cm. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the centrifuge relative centrifugal force calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the centrifuge relative centrifugal force result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
