How this tool gets the answer
What it calculates
Calculate adult body mass index from height and weight.
Method
BMI equals weight in kilograms divided by height in meters squared. Adult category wording follows CDC guidance; BMI is a screening measure, not a diagnosis.
Keep in mind
These adult equations do not diagnose health, account for every body type or circumstance, or replace individualized clinical assessment. This limitation is especially important when using the bmi calculator for a consequential or shared decision.
