Worked Example

Let's say you're a 30-year-old man who is 72 inches tall, has a waist measurement of 38 inches, and a neck measurement of 15 inches. Here's how you would use the calculator:

Select "Male" from the gender dropdown.
Enter "38" for waist measurement.
Enter "15" for neck measurement.
Enter "72" for height measurement.
Click the "Calculate" button.

Example Calculation

Using the formula for men:

Body Fat % = 86.010 × log10(38 - 15) - 70.041 × log10(72) + 36.76

Body Fat % ≈ 86.010 × log10(23) - 70.041 × log10(72) + 36.76

Body Fat % ≈ 86.010 × 1.3617 - 70.041 × 1.8551 + 36.76

Body Fat % ≈ 117.25 - 126.45 + 36.76

Body Fat % ≈ 27.57%

Based on this calculation, your body fat percentage is approximately 27.57%, which falls into the "Obese" category. This result suggests that you may want to consider making lifestyle changes to improve your health and fitness.
