Calculating body mass index, or BMI, is a low-cost, easy method to assess overweight and obesity based on height and weight. A BMI wheel makes the process even easier.
BMI = (
weight in pounds
) X 703
(height in inches) X (height in inches)
BMI = (
weight in kilograms
)
(height in inches) X (height in inches)
For adults over the age of 20, BMI falls into one of four groups: underweight, normal, overweight, and obese. For children, BMI is interpreted according to age and gender.
