Electricity
Watt hour: A watt hour is the amount of energy consumed by an appliance in one hour if it operates at a power of one watt. A watt-hour is too small a unit for most purposes, so we use the “kilowatt-hour” (kWh), which is equal to 1000 watt-hours. Kilowatt-hours are the units measured by electricity meters.
Watts: Volts x amperes
Kilowatt (kW) = 1000 watts
Megawatt (MW) = 1,000,000 watts
Gigawatt (GW) = 1,000,000,000 watts
Gas
Joule (J): A Joule is a unit of measure of energy; it is equivalent to passing electric current of one amp through a resistance of one ohm for one second.
Kilojoule (KJ) = 1000 joules
Megajoule (MJ) = 1000,000 joules
Terra joule (TJ) = 1,000,000,000,000
