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 (Ec)
The therm (EC) is a unit of energy used primarily in the measurement of natural gas and heating energy, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm originated in the early 19th century as a practical unit for measuring large quantities of heat energy, especially in the gas industry, and has been standardized in various regions for energy billing and calculations.
Current Use
Today, the therm (EC) is used mainly in the natural gas industry and energy sectors to quantify heat energy consumption, although it has largely been supplemented or replaced by SI units like joules and kilowatt-hours in many regions.
