Calculate Body Surface Area (BSA)







What is Body Surface Area (BSA)?

Body Surface Area (BSA) is a measurement used in many medical tasks, including determining the correct dosages for medications and assessing metabolic mass. It provides a more accurate measure of the body's surface area than simple height and weight measurements.

Formula

The Schlich formula for calculating BSA is given by:

For women:

BSA=0.000975482×W0.46×H1.08

For men:

BSA=0.000579479×W0.38×H1.24

where:

BSA Formula Step by Step Example Calculation

Let's assume the following values:

Using the formula for women:

BSA=0.000975482×700.46×1751.08

Calculating step-by-step:

700.467.06

1751.08264.534

BSA=0.000975482×7.06×264.5341.83m2

The calculated Body Surface Area (BSA) for a woman is approximately 1.83 m².
