About the units
British thermal unit (BTU)
About 1,055 joules (International Table value), used for heating and cooling.
Kilowatt-hour (kWh)
Exactly 3.6 megajoules: the "unit" on an electricity bill.
Energy is the capacity to do work. The SI unit is the joule. Food energy is labelled in kilocalories (Calories with a capital C) or kilojoules, electricity is billed in kilowatt-hours, and heating often uses BTU or therms.
