Body mass index (BMI)

Body mass index (BMI)

Adult screening BMI from height and weight, not a diagnosis.

Calculated result

24.69

Screening measure for adults (20+); does not assess muscle mass or individual health.

Results are estimates or simple arithmetic, not medical or investment advice.

How it works

Body mass index compares weight with height. For adults it is a screening measure, not a measure of body fat or a diagnosis.

Method and limitations

Divide kilograms by squared height in meters. CDC defines adult reference categories for ages 20 and older; ages 2–19 require a different age-specific approach.

BMI = weight (kg) ÷ height (m)².

Research source: CDC — Adult BMI Calculator
