kJ to J converter
1 kJ = 1,000 J
And 1 J = 0.001 kJ. Kilojoules to joules.
Formula
J = kJ × 1,000
A reading of 25 kJ is 25 × 1,000 = 25,000 J.

About these units
kJ (kilojoules): Thermal and mechanical energy in engineering calculations.
J (joules): The SI unit of energy: one newton metre.
The BTU used here is the International Table BTU (1,055.056 J). A foot-pound of energy (ft·lbf) is the same dimension as a lbf·ft of torque, but the two are different physical quantities.
