BSA is short for 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 since it’s less affected by irregular amounts of fat tissue.

**Formula to calculate BSA.**

We calculate BSA using the mosteller formula since its the simplest.

**Example:**

Suppose you are 150cm tall and weigh 70 Kg. Calculate your BSA.

Thus, your BSA is 1.71 m².
