Enter the age and body density into the calculator to determine the body fat percentage using the Jackson and Pollock equation.

Jackson and Pollock Body Fat Formula

The following formula is used to calculate the body fat percentage:

Body Fat = (495 / Body Density) - 450

Variables:

  • Body Density is measured in grams per cubic centimeter (g/cm³)
  • Body Fat Percentage is the percentage of fat in the body

To calculate the body fat percentage, divide 495 by the body density and then subtract 450.

What is the Jackson and Pollock Equation?

The Jackson and Pollock equation is a method to estimate body fat percentage based on body density. It was developed by Dr. Andrew Jackson and M.L. Pollock and is widely used in fitness and health assessments. The equation takes into account the density of the body, which can be measured using skinfold measurements and then converted to body density using established equations.

How to Calculate Body Fat Using Jackson and Pollock Equation?

The following steps outline how to calculate the body fat percentage using the Jackson and Pollock equation:


  1. First, determine the body density (in g/cm³).
  2. Next, use the Jackson and Pollock body fat formula: Body Fat (%) = (495 / Body Density) – 450.
  3. Finally, calculate the body fat percentage.
  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.

Age: 30 years

Body Density: 1.0700 g/cm³

Using the Jackson and Pollock body fat formula, the body fat percentage is calculated as follows:

Body Fat (%) = (495 / 1.0700) – 450 ≈ 12.85%
