Kilocalorie to Kilojoule Conversion Formula

To convert from Kilocalorie (kcal) to Kilojoule (kJ), use the following formula:

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

=1000×4.184×11000× Kilocalorie (kcal)= 1000 \times 4.184 \times \frac{1}{1000}\times \textbf{ Kilocalorie} \text{ (kcal)}

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

With 4.1844.184 is the ratio between the base units Joule (J) and calorie (cal).

Example

Let's convert 5 Kilocalorie (kcal) to Kilojoule (kJ).

Using the formula:

5×4.184=20.925 \times 4.184 = 20.92

Therefore, 5 Kilocalorie (kcal) is equal to 20.9220.92 Kilojoule (kJ).
