# G Force Calculator, Formula, G Force Calculation

## G Force Calculator:

Enter the values of radius of the rotor, R(cm) and rotation speed, RPM to determine the value of relative centrifugal force, G.

 Enter Radius of the Rotor: cm Enter Rotation Speed: RPM Result – Relative Centrifugal Force: m/s2

## G Force Formula:

The G-force formula for centrifuges calculates the relative centrifugal force experienced by samples within a centrifuge, which is essential for understanding the separation and sedimentation rates of different components under high-speed rotation.

G- Force, G(m/s2)  is calculated by the product of radius of the rotor, R(cm) in centimetres, square of rotation speed, RPM and 0.001118.

Relative centrifugal force, G(m/s2)  = 0.001118 * R(cm) * RPM

G(m/s2) = relative centrifugal force in metre per second square, m/s2.

R(cm) = radius of the rotor in centimetres, cm.

RPM = rotation speed in rotation per minute.

### G Force Calculation:

1. For a centrifuge with a 12 cm radius operating at 4000 RPM:

Given: R(cm) = 12cm, RPM = 4000.

Relative centrifugal force, G(m/s2)  = 0.001118 * R(cm) * RPM

G(m/s2) = 0.001118 * 12 * 4000

G(m/s2) =  213,888.

1. Calculate the radius required for a centrifuge to achieve a G-force of 500,000m/s2 at 3500 RPM.

Given: G(m/s2) =  500,000m/s2, RPM = 3500.

Relative centrifugal force, G(m/s2)  = 0.001118 * R(cm) * RPM

R(cm) =  G(m/s2)  / 0.001118 * RPM

R(cm) = 500,000 / 0.001118 * 3500

R(cm) = 36.44cm.
