What to understand
BMI uses weight in kilograms divided by the square of height in metres. Enter current measurements and check the units. The result does not directly measure body fat or explain your medical history, physical fitness or how weight is distributed. Adult and child assessments use different approaches.
02 · Weight & health
Plan the next step
Bring the result to a clinician alongside waist measurements, health history and the questions you want answered. Do not choose an aesthetic procedure or medicine from BMI alone. The calculator can help organise information, while an individual assessment determines what that information means for you.
03 · Weight & health
Are my measurements and units correct?
Check whether height is entered in centimetres and weight in kilograms. Correct an input error before interpreting the result.
04 · Weight & health
What other health information should we consider?
Bring the result to a health discussion alongside your history and other measurements. A calculator cannot replace an individual assessment.
05 · Weight & health
What does this result change about my next step?
Use the number to prepare questions, not to select a medicine or procedure. Ask what further context the clinician needs.
