Metric: BMI = weight (kg) ÷ height² (m²)
Imperial: BMI = (weight (lbs) ÷ height² (in²)) × 703

BMI is a useful general guideline but has limitations. It does not distinguish between muscle mass and fat mass. Highly muscular people may have a high BMI despite having low body fat.
Regular physical activity, a balanced diet, stress management, and adequate sleep all matter. For personalized advice, consult a healthcare professional.
A BMI between 18.5 and 24.9 is generally considered healthy for most adults. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is classified as obese.
