Enter the total energy in joules, distance, and mass into the calculator to determine the joules to g force.

Joules to G Force Formula

The following equation is used to calculate the Joules to G Force.

GF = J * m / d / 9.81
  • Where GF is the g-force from joules (g-force)
  • J is the number of joules (J)
  • m is the mass (kg)
  • d is the distance (m)

To calculate g-force from joules, multiply the joules by the mass, divide by the distance, then finally, divide by the acceleration due to gravity.

What is Joules to G Force?


Joules is a unit of energy, and g-force measures the relative acceleration compared to the acceleration due to gravity. To convert between the two units, you must convert joules to acceleration using the mass and distance, then divide by the value of the acceleration due to gravity.

How to Calculate Joules to G Force?

Example Problem:

The following example outlines the steps and information needed to calculate Joules to G Force.

First, determine the number of joules (J). In this example, the number of joules (J) is found to be 50 J.

Next, determine the mass. For this problem, the mass is found to be 2.3 kg.

Next, determine the distance. In this case, the distance is measured to be 20m.

Finally, calculate the Joules to G Force using the formula above:

J-GF = J * m / d / 9.81

J-GF = 50 * 2.3 / 20 / 9.81

J-GF = .586 g-forces
