Question 1

What is a Body Surface Area Calculator?

Accepted Answer

Body Surface Area (BSA) is the measured or calculated surface of a human body. It is used in clinical medicine primarily for calculating chemotherapy dosages, cardiac index, and burn surface area. BSA is more accurate than weight alone for drug dosing because it correlates better with metabolic rate.

Question 2

How does the Body Surface Area Calculator work?

Accepted Answer

DuBois & DuBois (1916): BSA = 0.007184 × height^0.725 × weight^0.425 Then: Mosteller (1987): BSA = √(height × weight / 3600) Then: Height in cm, weight in kg; BSA in m² Then: Average adult BSA: 1.73 m² (used as reference in eGFR).

Question 3

Can you give an example of how to use the Body Surface Area Calculator?

Accepted Answer

Example: Input 70 kg, 175 cm (DuBois) gives a result of BSA ≈ 1.84 m².
