Body Fat Percentage:

Definition: This calculator estimates body fat percentage using only BMI and age, without requiring body measurements.

Purpose: It provides a quick estimate of body fat percentage for individuals who know their BMI but don't have body measurements.

The calculator uses gender-specific formulas:

For Males: (1.20 × BMI) + (0.23 × Age) - 16.2
For Females: (1.20 × BMI) + (0.23 × Age) - 5.4

Where:

Explanation: These formulas estimate body fat percentage by accounting for the relationship between BMI, age, and typical body fat distribution.

Details: Body fat percentage is a better health indicator than weight alone, helping assess fitness levels and health risks.

Tips: Enter your gender, BMI (calculate using height and weight if unknown), and age. All values must be valid (BMI > 0, age 1-120).

Q1: How accurate is this method?
A: It provides a reasonable estimate (±3-5%) but is less accurate than measurements or DEXA scans.

Q2: Where can I calculate my BMI?
A: Use our BMI Calculator tool or divide weight (kg) by height (m) squared.

Q3: Why does gender matter in the calculation?
A: Women naturally carry more essential body fat than men (about 10-13% vs 2-5%).

Q4: What's a healthy body fat percentage?
A: For men: 8-19% (athletes) to 20-25% (average); Women: 21-28% (athletes) to 29-35% (average).

Q5: Can I use this for children?
A: No, these formulas are designed for adults (18+ years).
