About the units
Kilowatt-hour (kWh)
Exactly 3.6 megajoules: the "unit" on an electricity bill.
Therm (thm)
The US therm: 100,000 BTU, used for natural gas billing.
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.
