BSA Calculator Fujimoto formula

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:

$W$ is the weight in kilograms
$H$ is the height in centimeters

BSA Formula Step by Step Example Calculation

Let's assume the following values:

Weight: 70 kg
Height: 175 cm

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 m².
