Calculate Ellen's Body Surface Area (BSA) Using DuBois Formula

02 Dec 2021

What is the formula to calculate Ellen's BSA?

Calculate Ellen's BSA using the DuBois formula.

To calculate Ellen's BSA, we can use the DuBois formula, which requires converting her weight from lb to kg and her height from ft and in to cm.

Ellen's BSA or Body Surface Area can be calculated using the DuBois formula:

BSA = (Weight in kg)^0.425 * (Height in cm)^0.725 * 0.007184

First, we need to convert the weight and height measurements to the appropriate units.

Ellen's weight of 191 lb can be converted to kg by dividing by 2.205 (1 kg is approximately 2.205 lb).

191 lb / 2.205 lb/kg = 86.58 kg

Next, we need to convert Ellen's height of 4 ft 4 in to cm.

4 ft 4 in is equivalent to (4 * 12) + 4 = 52 inches.

52 inches * 2.54 cm/in = 132.08 cm

Now, we can calculate Ellen's BSA using the formula:

BSA = (86.58 kg)^0.425 * (132.08 cm)^0.725 * 0.007184 = 1.72 square meters

Therefore, Ellen's BSA is approximately 1.72 square meters.
