Common questions about BMI calculation
BMI (Body Mass Index) is a measure of body fat based on height and weight. It's calculated using the formula: BMI = weight (kg) / height (m)². For imperial units: BMI = (weight in pounds × 703) / (height in inches)².
According to WHO standards: Underweight (<18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (30+). These categories help assess health risks associated with weight.
BMI is a useful screening tool but has limitations. It doesn't account for muscle mass, bone density, or fat distribution. Athletes with high muscle mass may have higher BMI despite being healthy.
