Enter the weight and height into the calculator to determine the Body Surface Area (BSA) using the Dubois formula. This calculator helps in estimating the BSA which is often used in medical settings to calculate drug dosages and medical indicators.
Dubois Formula
The Dubois formula is used to estimate the body surface area (BSA) of a person. The formula is as follows:
text{BSA} = 0.007184 times text{Weight}^{0.425} times text{Height}^{0.725}
Variables:
- BSA is the body surface area in square meters (m²)
- Weight is the body weight in kilograms (kg)
- Height is the height in centimeters (cm)
To calculate BSA using the Dubois formula, multiply 0.007184 by the weight raised to the power of 0.425 and the height raised to the power of 0.725.
What is Body Surface Area (BSA)?
Body Surface Area (BSA) is a measure of the total surface area of the human body. It is used in various medical practices to calculate doses for chemotherapy, medication, and the amount of fluids to be administered intravenously. BSA is considered a more accurate measure of metabolic mass than body weight because it is less affected by abnormal adipose mass.
How to Calculate Body Surface Area?
The following steps outline how to calculate the Body Surface Area using the Dubois formula.
- First, determine the weight of the person in kilograms (kg).
- Next, determine the height of the person in centimeters (cm).
- Use the Dubois formula: BSA = 0.007184 * Weight0.425 * Height0.725.
- Finally, calculate the Body Surface Area (BSA) in square meters (m²).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Weight = 70 kg
Height = 175 cm
