The formula to calculate Kilojoules (kJ) from Calories (cal) is:
\[ E (\text{kJ}) = E (\text{cal}) \times 0.004184 \]
Where:
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^].
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.
