British Thermal Units (BTU)
Definition
A British Thermal Unit (BTU) is an imperial unit of energy defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It equals approximately 1,055.06 joules.
History
The BTU originated in the British imperial measurement system in the 19th century. Despite the global shift toward metric units, it remains entrenched in US, UK, and Canadian HVAC and energy industries.
Current use
BTUs are the standard unit for rating heating and cooling equipment (furnaces, air conditioners), measuring natural gas energy content, and comparing fuel efficiencies in North America.
Therms (US)
Definition
A therm is an imperial unit of heat energy equal to 100,000 BTU or approximately 105,506,000 joules. It is used primarily for natural gas billing.
History
The therm was defined by the UK Gas Act of 1920 for standardizing natural gas billing. It provided a convenient large-scale unit for measuring gas consumption across households and businesses.
Current use
Therms are used by natural gas utilities in the United States and the United Kingdom for billing residential and commercial customers. Gas bills typically show consumption in therms.
