Convert kilocalorie (th) to kilowatt-second
Please provide values below to convert kilocalorie (th) [kcal (th)] to kilowatt-second [kW*s], or Convert kilowatt-second to kilocalorie (th).
1 kcal (th) = 4.184 kW*s. To convert kilocalorie (th) to kilowatt-second, multiply the value by 4.184; to go the other way, divide by it (1 kW*s = 0.239005736138 kcal (th)). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kcal (th) = 4.184 kW*s
- 1 kW*s = 0.239005736138 kcal (th)
- 10 kcal (th) = 41.84 kW*s
- 100 kcal (th) = 418.4 kW*s
How to Convert Kilocalorie (Th) to Kilowatt-Second
1 kcal (th) = 4.184 kW*s
Example: convert 15 kcal (th) to kW*s:
15 kcal (th) = 15 × 4.184 kW*s = 62.76 kW*s

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.
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.
