BMI CalculatorFLAGSHIP
Calculate adult BMI as a general screening measure.
Adult BMI screening estimate
Calculate adult BMI from height and weight and place the result in CDC adult screening categories.
Method
BMI is weight in kilograms divided by height in meters squared. It is a screening measure, not a diagnosis or direct body-fat measurement.
Example
Two adults with the same BMI can have different body composition, so context matters.
