A megajoule is 1/3.6 of a kilowatt-hour so it costs about $0.05.
For example, suppose you want to calculate the energy of a 700 kilogram (kg) car moving at 20 meters per second (m/s). Plug the values into the kinetic energy equation to calculate the joules, as shown below: Kinetic Energy = 1/2 * 700 kg * 20^2 m/s = 140,000 joules. Calculating Joules of Work. Write the equation for work: Work = force * distance, where work is in joules, force is in newtons, and distance is in meters. Consider the situation for which you would like to calculate the joules of work being done.
