Watt-Second
A watt-second (W·s) is a unit of energy equivalent to one joule, representing the amount of energy transferred or converted when one watt of power is applied for one second.
History/Origin
The watt-second originated from the SI system of units, where the watt (W) is the SI derived unit of power, and the second (s) is the SI base unit of time. It has been used historically in physics and engineering to quantify energy, especially in contexts where energy transfer occurs over short durations.
Current Use
The watt-second is primarily used in scientific and engineering contexts to measure small amounts of energy, such as in electrical and mechanical systems. It is often replaced by the joule in modern applications but remains a recognized unit within the energy converter category.
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.
