1. What is the Body Fat Percentage Calculator?

The Ideal Body Fat Percentage Calculator estimates body fat percentage using a BMI-based formula that accounts for age and gender differences. This provides a more comprehensive assessment of body composition than BMI alone.

Explanation: This formula provides an estimation of body fat percentage using easily measurable parameters, though results may vary between different measurement methods.

3. Importance of Body Fat Percentage Calculation
