🔍 Body Fat Calculator – Measure Your Body Fat Percentage Accurately

Track your fitness progress and improve your health awareness with our professional Body Fat Calculator. Based on the U.S. Navy Method, this tool helps you estimate your body fat percentage using simple body measurements. Whether you're on a fitness journey, evaluating your current health status, or planning a weight management goal—this calculator provides an accurate, easy-to-understand insight into your body composition.

🧮 How the Calculator Works

This calculator uses gender-specific formulas that consider your height, neck, waist, and for females, hip circumference, along with your age and weight to calculate an estimate of your body fat percentage. The formula is based on logarithmic equations derived from body measurement data and is widely used for field assessments where advanced tools like DEXA scans are unavailable.

🧑 For Males:

Body Fat % = 86.010 × log10(waist - neck) − 70.041 × log10(height) + 36.76

👩 For Females:

Body Fat % = 163.205 × log10(waist + hip − neck) − 97.684 × log10(height) − 78.387

All values are first converted to inches and pounds for consistency with the formulas.
