calorie to Kilojoule Conversion Formula

To convert from calorie (cal) to Kilojoule (kJ), use the following formula:

$\textbf{ Kilojoule} \text{ (kJ)}$

$= 4.184 \times \frac{1}{1000}\times \textbf{ calorie} \text{ (cal)}$

$= 0.004184\times \textbf{ calorie} \text{ (cal)}$

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