## Energy from Carbs Formula

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

**E = C***4

Variables:

- Where E is the Energy from Carbs (kcal)
- C is the total number of carbs (grams)

## How to Calculate Energy from Carbs?

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

**Example Problem #1:**

- First, determine the total number of carbs (grams). In this example, the total number of carbs (grams) is measured to be 4.
- Finally, calculate the Energy from Carbs using the formula above:

E = C*4

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

E = 4*4 = 16 (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 number of carbs (grams) = 100

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

E = 100*4 = 400 (kcal)
