HEALTH & MEDICINE CALCULATOR
Bsa Calculator
A precise tool.
What is the Bsa Calculator & How does it work?
Body Surface Area (BSA) is a measurement used in medicine to estimate the amount of drugs, food, and other substances that should be administered to a patient. It helps in determining dosages based on the patient’s weight and height.
The most commonly used formula for calculating BSA is the Mosteller formula:
BSA = sqrt{frac{{weight(kg) times height(cm)}}{{3600}}}
BSA = Body Surface Area in square meters
weight(kg) = Weight of the patient in kilograms
height(cm) = Height of the patient in centimeters
weight(kg) = Weight of the patient in kilograms
height(cm) = Height of the patient in centimeters
This formula provides a good approximation for most adults and is widely used in clinical settings.

Frequently Asked Questions
How do I calculate BSA using the Mosteller formula?
Multiply the patient's weight in kilograms by their height in centimeters, then divide by 3600. Take the square root of the result to get the BSA in square meters.
What is the purpose of calculating Body Surface Area (BSA)?
BSA helps determine appropriate drug dosages based on a patient's weight and height, ensuring effective treatment.
Can I use this calculator for children?
Yes, you can use the Mosteller formula to calculate BSA for children as well, using their actual weight and height.
Are there other formulas to calculate BSA besides the Mosteller formula?
Yes, other formulas include Du Bois, Gehan and George, and Haycock. The Mosteller is one of the most commonly used due to its simplicity.
What units should I use for weight and height when calculating BSA?
For the Mosteller formula, use kilograms for weight and centimeters for height.
How accurate is the BSA calculation in determining drug dosages?
BSA calculations are a useful guide but should be adjusted based on individual patient factors and clinical judgment.
Can this calculator be used for adults only?
No, while it's commonly used for adults, the Mosteller formula can also be applied to children and some adult populations with specific needs.
