1. What is Body Fat Percentage?

Body fat percentage is the total mass of fat divided by total body mass, multiplied by 100. It provides a more accurate assessment of body composition than BMI alone, as it distinguishes between fat mass and lean body mass.

2. How Does the Calculator Work?

The calculator uses the formula for men:

Where:

• \( BMI \) — Body Mass Index (unitless)
• \( age \) — Age in years

Explanation: This formula estimates body fat percentage based on BMI and age, providing a quick assessment of body composition for men.

3. Importance of Body Fat Percentage

Details: Monitoring body fat percentage is important for assessing health risks, tracking fitness progress, and determining appropriate weight management strategies. High body fat percentage is associated with increased risk of various health conditions.

4. Using the Calculator

Tips: Enter your BMI value and age in years. Both values must be valid (BMI > 0, age between 1-120). For accurate results, ensure your BMI calculation is based on recent measurements.
