Body Surface Area (BSA) Calculator
Body Surface Area (BSA) Calculator – Accurate Health Tool
The Body Surface Area (BSA) Calculator helps estimate the total surface area of the human body using weight and height. It's an essential parameter in medicine, especially when prescribing dosages for chemotherapy, radiation, and other medical treatments. Our calculator uses the widely accepted DuBois and DuBois formula for high precision.
Why Is BSA Important?
Body Surface Area is more accurate than just weight alone when determining metabolic mass. It’s used extensively in healthcare for:
- Dosing certain medications
- Evaluating kidney and liver function
- Assessing burn severity
- Estimating cardiac output
How to Calculate BSA?
The most common method is the DuBois formula:
BSA = √[(height in cm × weight in kg) / 3600]
For example, a person with 170 cm height and 65 kg weight would have a BSA of approximately 1.77 m². This gives doctors a more accurate reference for therapeutic decisions.
