Kilocalorie to Megajoule Conversion Formula

To convert from Kilocalorie (kcal) to Megajoule (MJ), use the following formula:

$\textbf{ Megajoule} \text{ (MJ)}$

$= 1000 \times 4.184 \times \frac{1}{10^{6}}\times \textbf{ Kilocalorie} \text{ (kcal)}$

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

$= 0.004184\times \textbf{ Kilocalorie} \text{ (kcal)}$

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

Example

Let's convert 5 Kilocalorie (kcal) to Megajoule (MJ).

Using the formula:

$5 \times 0.004184 = 0.02092$

Therefore, 5 Kilocalorie (kcal) is equal to $0.02092$ Megajoule (MJ).
