Formula Used

The body fat percentage for women is calculated using the following formula:

Body Fat Percentage Formula

Body Fat Percentage = (495 / (1.0324 - 0.19077 × log10(waist - neck) + 0.15456 × log10(height))) - 450

This formula is based on anthropometric measurements and provides an estimate of body fat percentage for women. The measurements used are waist circumference, neck circumference, and height.

Interpreting Your Results

Understanding your body fat percentage is essential for assessing your overall health and fitness. Here's how to interpret your results:

Body Fat Percentage	Classification	Health Implications
Below 14%	Essential Fat	Very low body fat, may indicate malnutrition or genetic factors.
14-20%	Athletes	Typical for elite athletes, very lean body composition.
21-24%	Fitness	Excellent body composition, low body fat.
25-31%	Average	Typical for healthy individuals, moderate body fat.
32%	Obese	High body fat, may indicate health risks.

Worked Example

Let's walk through a worked example to demonstrate how the calculator works. Suppose you have the following measurements:

Height: 165 cm
Waist: 72 cm
Hip: 94 cm
Wrist: 14 cm
Forearm: 24 cm

Using the formula provided, we calculate the body fat percentage as follows:

Calculation Steps

1. Calculate the log10 of (waist - neck): log10(72 - 14) = log10(58) ≈ 1.7636

2. Calculate the log10 of height: log10(165) ≈ 2.2179

3. Plug these values into the formula: (495 / (1.0324 - 0.19077 × 1.7636 + 0.15456 × 2.2179)) - 450

4. Calculate the denominator: 1.0324 - (0.19077 × 1.7636) + (0.15456 × 2.2179) ≈ 1.0324 - 0.3392 + 0.3453 ≈ 1.0485

5. Divide 495 by the denominator: 495 / 1.0485 ≈ 471.8

6. Subtract 450: 471.8 - 450 ≈ 21.8%

Based on these measurements, your estimated body fat percentage is approximately 21.8%. This falls within the "Athletes" classification, indicating a very lean body composition.
