BMI & BSA Pro allows you to calculate the Body Mass Index and Body Surface Area for adults and for child and teen.

Body mass index (BMI) is a measure of body size. It combines a person’s weight with their height. The results of a BMI measurement can give an idea about whether a person has the correct weight for their height.
BMI is a screening tool that can indicate whether a person is underweight or if they have a healthy weight, excess weight, or obesity.

The body surface area (BSA) is the measured or calculated surface area of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass.
