No, BMI is a calculation using the height and weight in metric units. My BMI is 24.5(morning weight) and 25.5 (clinic weight in the afternoon with all my clothes). The bodyfat monitor uses bioelectrical impedance.. Body tissue such as muscles, blood vessels and bones have a high water content so they conduct electricity easily. Body fat has a lower conductivity so it judges your percentage of bodyfat by this conductivity.
