1. What is the Body Fat Percentage Formula?

The body fat percentage formula estimates body fat using BMI, age, and gender. This method provides a quick estimation of body composition based on easily measurable parameters.

2. How Does the Calculator Work?

The calculator uses the body fat percentage formula:

Where:

• \( \text{BMI} \) — Body Mass Index (weight in kg / height in m²)
• \( \text{age} \) — Age in years
• \( \text{sex} \) — 1 for male, 0 for female

Explanation: The formula estimates body fat percentage by combining BMI with age and gender adjustments to provide a more accurate assessment.

3. Importance of Body Fat Calculation

Details: Body fat percentage is a crucial health indicator that provides more insight than weight alone. It helps assess health risks associated with obesity and guides fitness and nutrition planning.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this body fat estimation method?
A: This method provides a reasonable estimation but may not be as accurate as more advanced methods like DEXA scans or hydrostatic weighing.

Q2: What are healthy body fat percentage ranges?
A: For men: 6-24% (athletes: 6-13%, fitness: 14-17%, average: 18-24%). For women: 16-30% (athletes: 14-20%, fitness: 21-24%, average: 25-30%).

Q3: Can this formula be used for all age groups?
A: The formula works best for adults. It may not be accurate for children, elderly, or highly trained athletes.

Q4: How often should I measure my body fat percentage?
A: For tracking progress, measure every 4-8 weeks. Daily measurements are not recommended due to normal fluctuations.

Q5: Are there limitations to this calculation method?
A: This method may be less accurate for individuals with very high muscle mass, pregnant women, or those with certain medical conditions.
