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.

Kilowatt-hours (kWh)

Definition

A kilowatt-hour (kWh) is a unit of energy equal to 1,000 watt-hours or 3,600,000 joules. It represents the energy consumed by a 1,000-watt appliance running for one hour.

History

The kilowatt-hour became the standard billing unit for electricity with the widespread electrification of homes and businesses in the early 20th century. Power utilities worldwide adopted it for metering.

Current use

Kilowatt-hours are the universal unit for residential and commercial electricity billing. They are also used to measure electric vehicle battery capacity, solar panel output, and grid-level energy storage.
