Web ResultApr 12, 2022 · The SI unit for Energy is the joule, usually abbreviated J. One joule is equal to one kilogram meter squared per second squared: \(\ 1 \mathrm{~J}=1 \frac{\mathrm{kg} \mathrm{m}^{2}}{\mathrm{~s}^{2}}\) Anything that is energy can be written as a number of joules. However, this isn’t the only unit for energy.
