1. What is the Body Fat Calculator?

The Body Fat Calculator estimates body fat percentage based on weight, height, age, and gender using a BMI-based formula. It provides a quick assessment of body composition.

2. How Does the Calculator Work?

The calculator uses the following formula for men:

Where:

• \( Weight \) — Body weight in kilograms (kg)
• \( Height \) — Height in meters (m)
• \( Age \) — Age in years

Explanation: The equation combines BMI (weight/height²) with age adjustment to estimate body fat percentage.

3. Importance of Body Fat Percentage

Details: Body fat percentage is a key indicator of health and fitness, more accurate than BMI alone for assessing body composition and health risks.

4. Using the Calculator

Tips: Enter weight in kg, height in meters, age in years, and select gender. All values must be valid (weight > 0, height > 0, age between 1-120).
