How is BMI calculated?

BMI = weight(kg) / height(m)^2. In Imperial mode, your height/weight are converted to metric for the calculation.

What BMI categories does this tool use?

It uses common adult thresholds: Underweight < 18.5, Normal 18.5–24.9, Overweight 25–29.9, Obese ≥ 30.

It shows the weight range that corresponds to BMI 18.5–24.9 for your entered height.

The tool estimates BMR using weight/height/age/gender and multiplies by your activity level to get daily calories (TDEE).
