Worked example
Example: 70 kg and 170 cm (5 ft 7 in).

How the BMI Calculator (kg, feet & age) works
Enter weight, height and age. BMI is weight in kilograms divided by height in metres squared, shown with WHO and Asian-Pacific categories and a healthy weight range.
Formula: BMI = Weight (kg) ÷ Height² (m²)
What to know before you calculate
BMI is a quick screening number, not a diagnosis, and it does not separate muscle from fat. For South Asians, health risk starts at a lower BMI than the standard WHO cut-offs, so both are shown.
Tips for accurate results
Health calculators are educational estimates and not a diagnosis. Consult a doctor or dietitian before making medical or major diet decisions.
