Kilocalories to Kilojoules Definition

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. Kilojoule (kJ) is a unit of energy, representing 1000 joules. The conversion from kilocalories to kilojoules is straightforward: multiply the energy in kilocalories by 4.184[^1^].

Example Calculation

Let's assume the following value:

Using the formula:

\[ E = 5 \times 4.184 \]

\[ E = 20.92 \text{ kJ} \]

The Energy (kJ) is 20.92 kJ.
