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.
Therm
A therm 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 by the American Gas Association to standardize natural gas billing and measurement; it became widely adopted in North America for energy calculations.
Current Use
Today, the therm is still used in the natural gas industry for billing and energy measurement, although other units like gigajoules and cubic meters are also common globally.
