Frequently Asked Questions

What is BMI and how is it calculated?
BMI (Body Mass Index) is a measure of body fat based on height and weight. The metric formula is weight (kg) ÷ height (m)². The imperial formula is (weight (lbs) × 703) ÷ height (in)².
What is a healthy BMI range?
A BMI between 18.5 and 24.9 is generally considered normal weight. Below 18.5 is underweight, 25–29.9 is overweight, and 30+ is classified as obese by the WHO.
Is BMI accurate for athletes or muscular people?
BMI does not distinguish between muscle and fat mass. Athletes with high muscle mass may have a high BMI but low body fat. Consider additional metrics like body fat percentage for a more complete picture.
Can I use this BMI calculator for children?
This calculator uses adult BMI categories. Pediatric BMI is assessed using age- and sex-specific percentile charts, which require a different tool.
