Enter the total body weight (lbs) and the fat weight (lbs) into the Body to Fat Ratio Calculator. The calculator will evaluate and display the Body to Fat Ratio.

## Body to Fat Ratio Formula

The following formula is used to calculate the Body to Fat Ratio.

**BFR = BW / F**

- Where BFR is the Body to Fat Ratio
- BW is the total body weight (lbs)
- F is the fat weight (lbs)

## How to Calculate Body to Fat Ratio?

The following example problems outline how to calculate Body to Fat Ratio.

Example Problem #1:

- First, determine the total body weight (lbs).
- The total body weight (lbs) is given as: 160.

- Next, determine the fat weight (lbs).
- The fat weight (lbs) is provided as: 40.

- Finally, calculate the Body to Fat Ratio using the equation above:

BFR = BW / F

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

BFR = 160 / 40 = 4.00:1

Example Problem #2:** **

For this problem, the variables required are provided below:

total body weight (lbs) = 200

fat weight (lbs) = 50

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