How It Works

BMI is calculated by dividing your weight in kilograms by the square of your height in metres: BMI = weight (kg) / height (m)². It provides a quick screening tool for weight categories.

BMI does not distinguish between muscle and fat mass. Athletes and muscular individuals may have a high BMI without excess body fat. For a complete picture, consider body composition measurements and consult a healthcare professional.

This calculator provides estimates only. BMI is a screening tool, not a diagnostic measure. Consult a healthcare professional for personalized advice.
