1. What is Body Fat Percentage?

Body fat percentage is the proportion of fat to total body weight. It provides a more accurate assessment of body composition than weight or BMI alone, helping to evaluate health risks associated with body fat levels.

2. How Does the Calculator Work?

The calculator uses the body fat estimation formula:

Where:

• \( BMI \) — Body Mass Index (unitless)
• \( age \) — Age in years
• \( sex \) — 1 for female, 0 for male

Explanation: This formula estimates body fat percentage based on BMI, age, and gender, providing a quick assessment of body composition.

3. Importance of Body Fat Measurement

Details: Monitoring body fat percentage is important for assessing health risks, tracking fitness progress, and maintaining optimal body composition. High body fat levels are associated with increased risk of various health conditions.

4. Using the Calculator

Tips: Enter your BMI value, age in years, and select your gender. Ensure all values are valid (BMI > 0, age between 1-120).
