G Force Calculator

Enter the total RPM and radius into the calculator to determine the g-force acting on a rotating object.

G Force Formula

The following equation is used to calculate the g-force of a rotating object or body.

G = .001118 * R * RPM^2

  • Where G is the G-Force
  • R is the radius of the rotation (meters)
  • RPM is the rotations per minute

G Force Definitoin

G force is defined as the total force felt on a rotating object due to angular acceleration. The term G force i used to compare this force to the force of gravity. i.e 2 Gs is two times the force of gravity.

G Force Example

How to calculate G Force?

  1. First, determine the radius of rotation.

    Measure the radius of rotation of the object.

  2. Next, determine the RPM.

    Calculate or measure the total number of rotations per minute.

  3. Finally, calculate the G Force.

    Calculate the G Force using the equation above.

FAQ

What is G Force?

G force, in the case of the above calculator, is a relative force acting on a rotating object.

Why is g force relative?

G force is relative because it’s a force compared to the force of gravity of earther. For example 2G’s of g-force is equal to twice the gravitational force Earth.
