Energy
Convert kilojoule (kJ) to kilowatt-hour (kWh). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 kJ = 0.0002777778 kWh
To convert kilojoule to kilowatt-hour, multiply the kJ value by 0.0002777778. To go the other way, divide by 0.0002777778 (or multiply by 3600).

Heat duties integrate to energy in kJ, MJ, or BTU; utilities are billed in kWh or MMBTU.
A calorie, a BTU, and a joule are all energy — keep the conversion factors handy when a spec mixes them.
Worked example. A energy of 3600 kJ is 1 kWh.
Multiply the value in kJ by 0.0002777778 to get kWh. For example, 10 kJ = 0.002777778 kWh.
1 kJ equals 0.0002777778 kWh.
