About this calculator
Categories follow the World Health Organization classification for adults: under 18.5 underweight, 18.5 to 24.9 normal, 25 to 29.9 overweight, 30 and above obesity. This is general information, not medical advice.
Amounts are shown without a currency symbol, so the calculator works for any currency: enter all values in the same one.
