Protein to Energy Calculator

Formula

The formula to calculate the energy from protein is:

$E = P \times 4$

Where:

$E$ is the Energy from Protein (kcal)
$P$ is the total grams of protein (g)

What is Energy from Protein?

Energy from protein refers to the amount of energy, measured in kilocalories (kcal), that is derived from the protein content in food. Each gram of protein provides approximately 4 kcal of energy. This calculation is important for understanding the nutritional value and energy contribution of protein in a diet.

Example Calculation

Let's assume the following value:

Total Grams of Protein (P) = 50 g

Using the formula to calculate the energy from protein:

$E = 50 \times 4 = 200$

The Energy from Protein (E) is 200 kcal.
