Therm (Us)
The therm (US) is a unit of energy used primarily to measure natural gas consumption, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm was introduced in the early 20th century as a practical unit for billing natural gas, standardizing energy measurement in the United States. It has been widely adopted in the energy industry for commercial and residential gas usage.
Current Use
Today, the therm (US) is still used in the natural gas industry for billing and energy calculations, although it has been largely supplemented by the gigajoule and other SI units in scientific contexts.
Watt-Hour
A watt-hour (W·h) is a unit of energy equal to the amount of energy transferred or used when one watt of power is sustained for one hour.
History/Origin
The watt-hour was established as a practical unit of energy measurement with the adoption of the International System of Units (SI) and has been used in electrical and energy industries to quantify energy consumption and storage since the 20th century.
Current Use
Watt-hours are commonly used to measure electrical energy consumption in household appliances, batteries, and energy storage systems, providing a convenient unit for billing, capacity ratings, and energy management.
