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.
Horsepower Hour
A horsepower hour (hp*h) is a unit of energy representing the amount of energy equivalent to one horsepower of power sustained over one hour of time.
History/Origin
The horsepower hour originated from the traditional unit of horsepower used to quantify engine power, combined with the hour to measure energy consumption or production over time. It has been used primarily in engineering and energy industries to express energy usage or capacity.
Current Use
Today, the horsepower hour is rarely used in practical applications, having been largely replaced by the joule and other SI units. However, it may still be referenced in historical data, legacy systems, or specific industries dealing with older measurement standards within the energy and mechanical sectors.
