FAQ
How is BMI calculated?
BMI = weight (kg) ÷ height² (m). Categories: under 18.5 underweight, 18.5–25 normal, 25–30 overweight, over 30 obese. It's an indicative measure and ignores muscle vs fat.
Is BMI an accurate health measure?
It's indicative. For athletes with high muscle mass it can mislead. Consult a doctor to assess health.
