About the units
Kilowatt-hour (kWh)
Exactly 3.6 megajoules: the "unit" on an electricity bill.
British thermal unit (BTU)
About 1,055 joules (International Table value), used for heating and cooling.
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.
