## Energy from Fat Formula

The following equation is used to calculate the Energy from Fat.

**Ef = F * 9**

Variables:

- Where Ef is the Energy from Fat (kcal)
- F is the total grams of fat (g)

## How to Calculate Energy from Fat?

The following two example problems outline the steps and information needed in order to calculate the Energy from Fat.

**Example Problem #1:**

- First, determine the total grams of fat (g). In this example, the total grams of fat (g) is measured to be 7.
- Finally, calculate the Energy from Fat using the formula above:

Ef = F * 9

Inserting the values from above and solving the equation with the imputed values gives:

Ef = 7 * 9 = 63 (kcal)

**Example Problem #2: **

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:

total grams of fat (g) = 8

Entering these values into the formula or calculator above gives us:

Ef = 8 * 9 = 72 (kcal)
