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 Fujimoto formula for calculating BSA is given by:

\[ \text{BSA} = 0.008883 \times W^{0.444} \times H^{0.663} \]

where:

BSA Formula Step by Step Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{BSA} = 0.008883 \times 70^{0.444} \times 175^{0.663} \]

Calculating step-by-step:

\[ 70^{0.444} \approx 6.59 \]

\[ 175^{0.663} \approx 30.70 \]

\[ \text{BSA} = 0.008883 \times 6.59 \times 30.70 \approx 1.78\, \text{m}^2 \]

The calculated Body Surface Area (BSA) is approximately 1.78 mĀ².
