Formula

The formula to calculate Kilocalories (kcal) from Kilojoules (kJ) is:

\[ E (\text{kcal}) = \frac{E (\text{kJ})}{4.184} \]

Where:

Kilojoules to Kilocalories Definition

Joule (J) is a unit of energy, representing the amount of work done when a force of one newton displaces an object by one meter. Kilojoule (kJ) is a unit of energy, representing 1000 joules. Kilocalorie (kcal) is a unit of energy, representing the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius. The conversion from kilojoules to kilocalories is straightforward: divide the energy in kilojoules by 4.184.

Example Calculation

Let's assume the following value:

Using the formula:

\[ E = \frac{5}{4.184} \]

\[ E = 1.195 \text{ kcal} \]

The Energy (kcal) is 1.195 kcal.
