Calculadora de IMC

According to the World Health Organization, a healthy BMI falls between 18.5 and 24.9. Below 18.5 is classified as underweight, 25–29.9 as overweight, and 30 or above as obese. These ranges apply to adults aged 20 and older.

BMI does not distinguish between muscle mass and fat mass. Athletes or people with significant muscle development may have a high BMI while having low body fat. In these cases, a body fat percentage measurement provides a more accurate picture of health.

With imperial units, BMI is calculated as (weight in pounds × 703) ÷ (height in inches)². For example, a person weighing 154 lbs and standing 5'9" (69 inches) has a BMI of (154 × 703) ÷ (69²) = 22.7.

A prestação mensal é calculada utilizando a fórmula padrão de amortização com base no valor principal, taxa de juros e prazo total.

For adults, the same BMI thresholds apply regardless of age. However, for children and teenagers (ages 2–19), BMI is interpreted using age- and sex-specific percentiles because body composition changes significantly during growth.

BMI is a simple ratio of weight to height and does not measure body composition directly. Body fat percentage measures the actual proportion of fat tissue in your body. Two people can have the same BMI but very different body fat levels depending on their muscle mass.
