BSAcalc is a free software that helps calculate Body Surface Area (BSA) and Body Mass Index (BMI) with a variety of formulas. It has an easy-to-use and user-friendly interface for convenient usage.

BSAcalc stands out from other BSA calculation programs due to its large selection of formulas for calculation. Furthermore, the latest updates to BSAcalc now include the Body Mass Index (BMI) calculation.
BMI is a simple index of weight-for-height that has been used by the World Health Organization (WHO) since the early 1980s to record obesity statistics. BSAcalc's integration of the BMI feature allows users to classify underweight, overweight, and obesity in adults, simply by dividing the weight in kilograms by the square of the height in meters (kg/m2).
BSAcalc's simple and convenient user interface makes it an easy-to-perform method of screening for weight categories that may lead to health problems. Given its comprehensive formula selection and integration of BMI calculation, BSAcalc is an essential tool for clinicians and researchers in the field of medicine and physiology.
Version 1.5: The new formula for calculation body surface area (Lee JY et al., 2008) is added. Menu Bar to the BSAcalc is added. Access to the references from the menu is added. Requires a valid Internet account and browser software.
