The Mathematical formula
BMI = Weight (kg) / [Height (m)]²
BMI is a proxy for body fatness. While it doesn't measure body fat directly, research has shown that BMI is moderately correlated with more direct measures of body fat obtained from skinfold thickness measurements, bioelectrical impedance, underwater weighing, and other methods.
