Calculate your Body Mass Index and estimate body fat percentage using the clinically validated US Navy formula.
—
BMI (Body Mass Index) is calculated by dividing your weight in kilograms by the square of your height in meters. It's a simple screening tool used to classify weight categories, though it doesn't directly measure body fat or account for muscle mass.
This calculator uses the US Navy circumference method, which estimates body fat percentage from neck, waist, and hip measurements. Research shows this method is accurate to within 3–4% for most people, making it one of the most reliable non-invasive approaches available.
