Enter the total number of carbs (grams) into the calculator to determine the Energy from Carbs. 

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)
