Calories to Kilojoules Definition

Calorie (cal) is a unit of energy, representing the amount of energy needed to raise the temperature of one gram of water by one degree Celsius. Kilojoule (kJ) is a unit of energy, representing 1000 joules. The conversion from calories to kilojoules is straightforward: multiply the energy in calories by 0.004184[^1^].

Example Calculation

Let's assume the following value:

Using the formula:

\[ E = 500 \times 0.004184 \]

\[ E = 2.092 \text{ kJ} \]

The Energy (kJ) is 2.092 kJ.
