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.
Calorie (Nutritional)
A calorie (Cal) is a unit of energy used to measure the amount of energy provided by food and beverages, specifically representing the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie was first introduced in the 19th century as a unit to quantify energy in nutrition. It has since become a standard measure in dietary and nutritional contexts, although the scientific community often prefers the joule as the SI unit of energy.
Current Use
Calories are widely used in nutrition to quantify the energy content of food and beverages, helping consumers manage dietary intake and energy balance. The term 'Calorie' with a capital 'C' typically refers to kilocalories (kcal), which are equivalent to 1,000 small calories.
