Enter the total amount of protein (g) into the Protein Energy Ratio Calculator. The calculator will evaluate and display the total energy from protein.

## Protein Energy Ratio Formula

The following formula is used to calculate the Protein Energy Ratio.

**E = P * 4**

- Where E is the Energy (kcals)
- P is the total amount of protein (g)

## How to Calculate Protein Energy Ratio?

The following example problems outline how to calculate Protein Energy Ratio.

Example Problem #1:

- First, determine the total amount of protein (g).
- The total amount of protein (g) is given as: 50.

- Finally, calculate the Protein Energy Ratio using the equation above:

E = P * 4

The values given above are inserted into the equation below and the solution is calculated:

E = 50 * 4 = 200 (kcals)

Example Problem #2:** **

For this problem, the variables required are provided below:

total amount of protein (g) = 60

Test your knowledge using the equation and check your answer with the calculator above.

E = P * 4** = ?**
