1. What is the Body Fat Percentage Equation?

The Body Fat Percentage equation estimates body fat from BMI, age, and gender. It provides a simple way to assess body composition without specialized equipment.

2. How Does the Calculator Work?

The calculator uses the Body Fat Percentage equation:

Where:

• \( BMI \) — Body Mass Index (kg/m²)
