Kilocalorie to Watt-second Conversion Formula

To convert from Kilocalorie (kcal) to Watt-second (Ws), use the following formula:

$\textbf{ Watt-second} \text{ (Ws)}$

$= 1000 \times 4.184\times \textbf{ Kilocalorie} \text{ (kcal)}$

$= 4184\times \textbf{ Kilocalorie} \text{ (kcal)}$

With $4.184$ is the ratio between the base units Joule (J) and calorie (cal).

Example

Let's convert 5 Kilocalorie (kcal) to Watt-second (Ws).

Using the formula:

$5 \times 4184 = 20920$

Therefore, 5 Kilocalorie (kcal) is equal to $20920$ Watt-second (Ws).
