Joules
The joule (J) is the SI unit of energy. It is named after the English physicist James Prescott Joule. It is the amount of work done when a force of one newton moves an object by one meter in the direction of the force also known as a newton-meter.
Therm
The therm is a unit of heat energy used in the United States and the United Kingdom for measuring natural gas consumption.
Therm (US)
The Therm (US) is a unit of heat energy commonly used in the United States, particularly in the context of natural gas consumption. It is the amount of energy equivalent to burning 100 cubic feet of natural gas and is equivalent to about 105,480,400 joules.
Therms (UK)
The therm (UK) is a unit of heat energy primarily used in the United Kingdom to measure the energy content of natural gas. It is defined as 100,000 British thermal units (BTUs) which is approximately 105.5 megajoules (MJ).
Therm (EC)
The Therm (EC) is a unit of energy primarily used in the United Kingdom for billing purposes in the gas industry. It is defined as 105.5 megajoules (MJ). The "EC" in Therm (EC) stands for European Community as it was created to standardize within European countries.
