About BMI

Body Mass Index (BMI) is a measure of body fat based on height and weight. It applies to adult men and women. BMI does not account for muscle mass, bone density, or body composition. Consult a healthcare professional for a comprehensive health assessment.

Imperial: BMI = (weight in lbs / height in inches^2) x 703

Metric: BMI = weight in kg / (height in m)^2
