Kilowatt-Second
A kilowatt-second (kW·s) is a unit of energy equal to the energy transferred or converted when a power of one kilowatt is applied for one second.
History/Origin
The kilowatt-second has been used historically in physics and engineering to quantify energy, especially in contexts where power and time are relevant, but it is less common than other energy units like joules or kilowatt-hours.
Current Use
Today, the kilowatt-second is primarily used in specialized fields such as electrical engineering and energy calculations, often for convenience in measuring short-term energy transfer, but it is largely replaced by the joule in most applications.
Kilowatt-Hour
A kilowatt-hour (kW·h) is a unit of energy equal to the energy transferred or used when a power of one kilowatt is sustained for one hour.
History/Origin
The kilowatt-hour originated in the late 19th century with the development of electrical power systems, becoming a standard unit for measuring electrical energy consumption and billing.
Current Use
It is widely used today in electricity billing, energy consumption monitoring, and in various engineering and scientific applications to quantify electrical energy usage.
