Body Density Calculator

Formula

The formula to calculate body density is:

\[ \text{D} = 1.1422 - [0.0544 \times \log(\text{skinfold sum})] \]

Where:

(D) is the body density (g/m³)
(skinfold sum) is the sum of the skinfold measurements of the biceps, triceps, subscapular, and iliac (mm)

What is Body Density?

Body density is defined as the total mass per unit volume of an individual human. It’s often estimated using a formula like the one above, which takes skinfold measurements throughout the body.

Example Calculation

Let's assume the following values:

Skinfold Sum = 50 mm
Age = 35
Gender = Male

Using the formula:

\[ \text{D} = 1.1422 - [0.0544 \times \log(50)] = 1.1422 - [0.0544 \times 1.69897] = 1.1422 - 0.0924 = 1.0498 \]

The body density is 1.0498 g/m³.
