BMI Calculators
BMI calculators that answer what your BMI means for your height, and nothing else: the BMI calculator works out your BMI from height and weight in metric or imperial units, places it in the standard or Asian-cutoff band, and converts that band into a healthy weight range for your exact height, plus how much to lose or gain to reach it — with the math shown and no diagnosis implied.

On standard WHO bands, 18.5–24.9. The BMI calculator converts that band into a weight range for your exact height: at 1.75 m it is 56.7–76.3 kg, and at 5 ft 10 in it is 128.9–173.5 lb. With Asian cutoffs the healthy ceiling drops to 22.9, so the same 1.75 m height tops out at 70.1 kg instead.
No — BMI is weight relative to height, not a body-fat measurement. It cannot tell muscle from fat, so athletes can score overweight without excess fat and older adults can score healthy while carrying excess fat. Treat it as a first check, not a final word, and pair it with waist circumference or a body-composition measure for the fuller picture.
