BMI Calculator

How to Use Enter your height (cm) and weight (kg). Your BMI is calculated instantly. Your classification (underweight, normal, overweight, obese) is shown alongside the healthy weight range for your height. Toggle between metric (cm/kg) and imperial (ft/lb) units. Who Is This For Anyone starting a diet or fitness plan who wants a baseline health metric, people who want to know their healthy weight range, and individuals preparing for a medical checkup. Key Features • BMI (Body Mass Index) calculation • WHO classification display • Healthy weight range for your height • Suggested weight targets • Metric and imperial unit support Frequently Asked Questions Q: Can someone have a normal BMI but still be unhealthy? A: Yes. BMI doesn't account for muscle mass or fat distribution. Body fat percentage and waist circumference are more comprehensive indicators. Q: Are Asian BMI thresholds different from the WHO standard? A: Yes. The Asia-Pacific guidelines classify overweight as BMI ≥ 23 and obese as BMI ≥ 25, which is lower than the WHO standard (25/30). Q: Is BMI accurate for children and teenagers? A: No, children use age-specific growth charts with BMI-for-age percentiles, not fixed adult thresholds. Tips Even if your BMI is in the normal range, central obesity (high waist circumference) is a significant metabolic risk factor. Regular exercise and a balanced diet matter more than hitting a specific BMI number.
