Enter your height in centimeters and your weight in kilograms. This calculator uses the Mosteller formula to estimate your body's total surface area in square meters (m²).
❓ Frequently Asked Questions
What is BSA used for? +
Body Surface Area is primarily used in medicine to calculate precise dosages for drugs (like chemotherapy) and to assess cardiac index.
What is the average BSA? +
For an average adult man, the BSA is about 1.9 m², and for an average adult woman, it is approximately 1.6 m².
Is BSA better than BMI? +
While BMI measures body fatness, BSA is a more accurate indicator of metabolic mass and is preferred for clinical calculations.
What is the Mosteller formula? +
It is a simple and accurate calculation: Multiply height (cm) by weight (kg), divide by 3600, and then take the square root.
How does BSA affect metabolism? +
Generally, a larger BSA indicates a higher metabolic rate, as more surface area leads to more heat loss and energy requirement.
