# How do you calculate total calories of a protein?

Jul 11, 2018

Protein contains $4$ calories per gram.

#### Explanation:

If you know the mass of the protein, you can calculate its total calorie amount.

If we were to create an equation, it would look like this.

$\text{grams" * 4= " calories}$

For example, say you have $6.5$ grams of protein.

$6.5 \cdot 4 = 26 \text{ calories}$

Protein has the same amount of calories per gram as carbohydrates, although fats have $9$ calories per gram.
