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.
Kilocalorie (Th)
A kilocalorie (kcal) is a unit of energy equal to 1,000 calories, commonly used to measure the energy content of food and beverages.
History/Origin
The kilocalorie originated in the 19th century as a unit to quantify heat energy, especially in nutrition and thermodynamics. It was widely adopted in the early 20th century for dietary energy measurement.
Current Use
Today, the kilocalorie is primarily used in nutrition to express the energy content of food and drinks, although it is often simply called a 'calorie' in everyday language.
