1. What is Body Fat Percentage?

Body fat percentage is the proportion of fat to total body weight. It's a more accurate indicator of fitness than body weight alone, as it distinguishes between fat mass and lean body mass.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Fat \) — Fat mass in kilograms
• \( Weight \) — Total body weight in kilograms

Explanation: This calculation provides the percentage of your total weight that comes from fat.

3. Importance of Body Fat Measurement

Details: Knowing your body fat percentage helps assess health risks, track fitness progress, and set appropriate weight management goals. Healthy ranges vary by age and gender.

4. Using the Calculator

Tips: Enter fat mass and total weight in kilograms. Both values must be positive numbers, and fat mass cannot exceed total weight.
