BMI = 70 ÷ (1.75)² = 70 ÷ 3.0625 = 22.9

Imperial Formula (pounds e inches)

BMI = [weight in pounds ÷ (height in inches)²] × 703

Exemplo: A person weighing 154 lb who é 69 inches (5'9") tall:
BMI = [154 ÷ (69)²] × 703 = [154 ÷ 4761] × 703 = 0.0324 × 703 = 22.8

18.5 – 24.9	Normal weight

Doesn't Consider Fat Distribution

Onde you carry weight matters. Abdominal fat (apple shape) poses mais health risks than hip/thigh fat (pear shape). BMI doesn't capture este.

Age e Gender Differences

Women naturally carry mais body fat than men at o mesmo BMI. Older adults may têm healthy BMIs but unhealthy body composition.

Ethnic Variations

Padrão BMI categories foram developed from European populations. Alguns health organizations use diferente cutoffs for Asian populations (overweight at 23+, obese at 27.5+).

Alternative Metrics
