1. What is a Body Fat Percentage Calculator?

Definition: This calculator estimates your body fat percentage based on your BMI, age, and gender using scientifically validated formulas.

Purpose: It helps individuals assess their body composition and health risks associated with body fat levels.

2. How Does the Calculator Work?

The calculator uses different formulas for males and females:

Male: \[ \text{Body Fat %} = (1.20 \times \text{BMI}) + (0.23 \times \text{Age}) - 16.2 \]
Female: \[ \text{Body Fat %} = (1.20 \times \text{BMI}) + (0.23 \times \text{Age}) - 5.4 \]

BMI — Body Mass Index (weight in kg / height in m²)
Age — In years

Explanation: These formulas estimate body fat percentage based on population studies and correlations between BMI, age, and actual body fat measurements.
