1. What is the Body Fat Percentage Formula?

The Body Fat Percentage Formula estimates body fat percentage from BMI, age, and sex. It provides a convenient method to assess body composition using easily obtainable measurements.

2. How Does the Calculator Work?

The calculator uses the Body Fat Percentage Formula:

Where:

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

Explanation: The equation accounts for the relationship between BMI, age, sex and body fat percentage, providing an estimate of body composition.

3. Importance of Body Fat Percentage Calculation
