InterpretationThis is an estimated range
BMI is a screening measure, not a direct measurement of body fat or health. Results use the CDC adult reference interval.
Not a diagnosisFor general health education and estimation only. It does not diagnose a condition and is not treatment, medication, diet or training advice.
01Formula used
BMI = weight (kg) / height (m)²Suitable population
Adults aged 20 or older who are not pregnant, for rough screening only.
02When not to use it
Children, teenagers, pregnancy, competitive athletes, very muscular people and people with oedema require different interpretation.
Data error and uncertainty
Input accuracy, measurement technique, rounding and individual variation all affect the result. Internal precision is retained and only displayed values are rounded.
03When to seek help
Seek professional advice for a markedly high or low result, rapid unexplained weight change, or concerning symptoms.
