Everything About BMI Calculation
BMI (Body Mass Index) is an international indicator that conveniently assesses obesity using only height and weight. Calculated by dividing weight (kg) by height (m) squared, it classifies underweight, normal, overweight, and obese based on WHO and regional standards. Regular BMI monitoring is an important first step in health management.
Note that WHO international standards differ from Asian/Korean standards. WHO considers 18.5-24.9 normal, while the Korean Society for the Study of Obesity sets 18.5-22.9 as normal. Asians tend to have higher body fat percentages at the same BMI compared to Western populations, hence the stricter threshold.
This tool provides your healthy weight range alongside the BMI value. It shows what weight range corresponds to normal BMI (18.5-22.9) for your height, helping set realistic target weights. However, since BMI does not account for muscle mass, active individuals should also measure body fat percentage.
Pro tip: BMI is one reference indicator of health, not an absolute standard. People with the same BMI but different muscle-to-fat ratios have different health profiles. Track your BMI regularly to observe trends, and review lifestyle habits if sudden changes occur. Setting specific targets like "reach BMI 22" helps with diet motivation.
