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 Mosteller formula for calculating BSA is given by:

\[ \text{BSA} = 0.016667 \times W^{0.5} \times H^{0.5} \]

where:

BSA Formula Step by Step Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{BSA} = 0.016667 \times 70^{0.5} \times 175^{0.5} \]

Calculating step-by-step:

\[ 70^{0.5} \approx 8.37 \]

\[ 175^{0.5} \approx 13.23 \]

\[ \text{BSA} = 0.016667 \times 8.37 \times 13.23 \approx 1.847\, \text{m}^2 \]

The calculated Body Surface Area (BSA) is approximately 1.847 mĀ².
