1. What is Body Fat Percentage?

Body fat percentage is the proportion of fat in your body compared to your total body weight. This calculator provides an estimate of body fat percentage for women based on body measurements.

2. How Does the Calculator Work?

The calculator uses the following formula specifically designed for women:

Where:

• \( \text{waist} \) — Waist circumference in cm
• \( \text{hip} \) — Hip circumference in cm
• \( \text{neck} \) — Neck circumference in cm
• \( \text{height} \) — Height in cm

Explanation: The formula accounts for body proportions and uses logarithmic transformations to estimate body fat percentage based on circumference measurements.

3. Importance of Body Fat Measurement

Details: Knowing your body fat percentage helps assess health risks, track fitness progress, and determine appropriate weight management strategies more accurately than BMI alone.

4. Using the Calculator

Tips: For accurate results:

• Measure waist at the narrowest point
• Measure hips at the widest point
• Measure neck below the larynx
• All measurements should be in centimeters

Q4: Can this be used during pregnancy?
A: No, the formula is not valid during pregnancy due to body composition changes.

Q5: How often should I measure?
