Enter the density (g/cm^3) into the Calculator. The calculator will evaluate the body fat percentage from the Brozek Equation. 

Brozek Equation Formula

BF = (4.57/p - 4.142) * 100


  • BF is the Brozek Equation (body fat percentage (%))
  • p is the density (g/cm^3)

How to Calculate Brozek Equation?

The following steps outline how to calculate the Brozek Equation.

  1. First, determine the density (g/cm^3). 
  2. Next, gather the formula from above = BF = (4.57/p – 4.142) * 100.
  3. Finally, calculate the Brozek Equation.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

density (g/cm^3) = 3.585
