Convert kilocalorie (th) to watt-second
Please provide values below to convert kilocalorie (th) [kcal (th)] to watt-second [W*s], or Convert watt-second to kilocalorie (th).
1 kcal (th) = 4184 W*s. To convert kilocalorie (th) to watt-second, multiply the value by 4184; to go the other way, divide by it (1 W*s = 0.000239005736138 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) = 4184 W*s
- 1 W*s = 0.000239005736138 kcal (th)
- 10 kcal (th) = 41840 W*s
- 100 kcal (th) = 418400 W*s
How to Convert Kilocalorie (Th) to Watt-Second
1 kcal (th) = 4184 W*s
Example: convert 15 kcal (th) to W*s:
15 kcal (th) = 15 × 4184 W*s = 62760 W*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.
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.
