Frequently Asked Questions
BMI (Body Mass Index) is a measure of body fat based on height and weight that applies to adult men and women. It is a widely used screening tool to categorize basic weight status.
No. BMI does not measure body fat directly and it doesn't account for age, sex, bone structure, or muscle mass. Athletes for instance, may have a high BMI due to muscle mass rather than fat.
The formula is weight (kg) divided by the square of height (m). For imperial units, it is [weight (lb) / height (in)²] × 703.
