Your body mass index and category — in imperial or metric.
Body mass index is weight divided by height squared — in metric it's kilograms ÷ metres², and in imperial it's pounds ÷ inches² × 703, which is just the same formula with a unit-conversion factor folded in. The standard adult categories are: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, and 30 or above obesity. Because BMI uses only height and weight, it can over-state body fat for very muscular people and under-state it for others, and it isn't meant for children, who use age-and-sex percentile charts instead. It's best read as a population-level screening number, not a verdict on an individual's health. To convert between units yourself, the unit converter handles weight and length.
