Body Mass Index estimates whether your weight is healthy for your height. It is a quick screening tool, not a diagnosis — it does not distinguish muscle from fat.

⚠️ Limitations:
BMI, devised by Adolphe Quetelet (1832), turns weight and height into a single number that the WHO and clinicians use as a screening tool for weight-related risk.
Metric divides weight in kg by height in metres squared. Imperial uses (lb × 703) ÷ inches². This calculator converts automatically whichever units you enter.
BMI Prime is your BMI ÷ 25; 1.0 sits exactly at the upper healthy limit. The Ponderal Index divides weight by height cubed and is slightly more reliable for very tall or short people.
The WHO Asia-Pacific thresholds are lower: overweight starts at 23 and obesity at 27.5. Toggle to Asia-Pacific if that scale fits you better.
BMI only compares weight to height. A muscular athlete can read as "obese" while being healthy, so treat BMI as a starting point — your doctor makes the final call.
