J to kJ converter
1 J = 0.001 kJ
And 1 kJ = 1,000 J. Joules to kilojoules.
Formula
kJ = J × 0.001
A reading of 25 J is 25 × 0.001 = 0.025 kJ.

About these units
J (joules): The SI unit of energy: one newton metre.
kJ (kilojoules): Thermal and mechanical energy in engineering calculations.
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.
