Convert calorie (nutritional) to watt-second
Please provide values below to convert calorie (nutritional) [Cal] to watt-second [W*s], or Convert watt-second to calorie (nutritional).
1 Cal = 4186.8 W*s. To convert calorie (nutritional) to watt-second, multiply the value by 4186.8; to go the other way, divide by it (1 W*s = 0.000238845896627 Cal). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Cal = 4186.8 W*s
- 1 W*s = 0.000238845896627 Cal
- 10 Cal = 41868 W*s
- 100 Cal = 418680 W*s
How to Convert Calorie (Nutritional) to Watt-Second
1 Cal = 4186.8 W*s
Example: convert 15 Cal to W*s:
15 Cal = 15 × 4186.8 W*s = 62802 W*s

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.
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.
