Calories to Energy (Joules) Calculator

Formula

To calculate the energy in joules from calories:

\[ E(J) = E(kcal) \times 4184 \]

Where:

\(E(J)\) is the energy in Joules
\(E(kcal)\) is the total number of calories (in kilocalories)
4184 is the conversion factor from kilocalories to Joules

What is Energy in Joules?

Energy in Joules is a measure of the amount of energy transferred or converted. The joule is the standard unit of energy in the International System of Units (SI). One kilocalorie (kcal) is equivalent to 4184 joules (J). Therefore, to convert calories to joules, you multiply the number of kilocalories by 4184.

Example Calculation 1

Let's assume the following value:

Total Calories (kcal) = 5

Using the formula:

\[ E(J) = 5 \times 4184 = 20920 \text{ J} \]

Energy: 20,920 J

Example Calculation 2

Let's assume the following value:

Total Calories (kcal) = 10

Using the formula:

\[ E(J) = 10 \times 4184 = 41840 \text{ J} \]

Energy: 41,840 J
