Body Surface Area (BSA) Calculator: Used in health and medical settings.
Body Surface Area (BSA) Calculator: Obtain a precise calculation of Body Surface Area (BSA), an essential biometric indicator in medicine. BSA is crucial for determining medication dosages (especially in chemotherapy), fluid therapy in burn victims, and various clinical assessments, ensuring safer and more effective treatments.

How to Use the Calculator
1. Select Units: Choose between Metric (kilograms, centimeters) or Imperial (pounds, feet, inches).
2. Enter Weight: Type your weight into the designated field.
3. Enter Height: Fill in your height. If using Imperial, be sure to enter both feet and inches.
4. Calculate: Click the "Calculate BSA" button to see the results from five different common formulas.
What is Body Surface Area (BSA)?
Body Surface Area (BSA) is the measured or calculated total surface area of a human body. In medicine, BSA is a more accurate indicator of metabolic mass than body weight, as it is less affected by abnormal adipose mass. Consequently, it is a common measurement used to calculate the dosage of certain medications, especially chemotherapy drugs and intravenous fluids.
Explanation of Formulas
Mosteller: Published in 1987, this is the simplest and most commonly used formula today due to its ease of calculation.
DuBois & DuBois: One of the earliest formulas (1916), it was derived from direct measurements of a small number of subjects but remains highly validated and widely used.
Haycock: Developed in 1978, this formula is frequently used in pediatrics and for children, as it was derived from a study of infants, children, and adults.
Gehan & George: Created in 1970, this formula was developed from a large dataset and is another reliable option, though less common than Mosteller.
Boyd: A more complex formula from 1935 that is also highly accurate but less frequently used in clinical practice due to its complexity.
Glossary
BSA (Body Surface Area): The total surface area of the human body, measured in square meters (m²).
Metabolic Mass: The part of the body that is actively using energy. BSA is often a better proxy for this than simple weight.
Chemotherapy: Cancer treatment using cytotoxic drugs. Dosages are often calculated based on a patient's BSA to ensure safety and effectiveness.
BMI (Body Mass Index): A measure of body fat based on height and weight. While related, it is different from BSA, which measures total surface area.
