Joules to Force Calculator solves force, work energy, or distance with J, kJ, Wh, N, lbf, metric and US lengths, plus angled-force and equivalent-mass results.

Constant average force over straight displacement; use 0° when force acts parallel to motion.

Joules to Force Formula

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

F = J / d
  • Where F is the force (N)
  • J is the number of joules of work (joules)
  • d is the distance over which the work was performed

To calculate force from joules, divide the total number of joules by the total distance.

Assumes distance of 1 meter. Work = Force × Distance, so Force (N) = Energy (J) ÷ Distance (m). With d = 1 m, 1 J corresponds to 1 N.

Can Joules be Converted to Force?

Yes, joules can be converted to force if the work's distance is known. Joules is a unit of force times distance, so to figure force, you must know distance.

How to Convert Joules to Force?

Example Problem:

The following example outlines the steps and information needed to calculate force from joules.

First, determine the total amount of joules. For this problem, the total work done in joules is 500 J.

Next, determine the total distance. In this case the joules of work were done over a distance of 10m.

Finally, calculate the force from joules using the formula above:

F = J / d

F = 500 / 10

F = 50 N
