Body Surface Area (BSA) is an essential measurement used in healthcare to assess drug dosages, medical treatments, and physiological evaluations. Accurate calculation of BSA is crucial for doctors, nurses, and health enthusiasts who want precise results for medication administration, especially in chemotherapy and pediatric dosing. Our BSA Calculator simplifies this process, providing instant results based on your weight and height.
BSA Calculator
What is BSA?
BSA represents the total surface area of the human body, usually expressed in square meters (m²). Unlike body weight or BMI, BSA considers both height and weight, making it a more accurate predictor for medical purposes. BSA is widely used in:
- Determining the correct medication dosage
- Assessing fluid requirements
- Evaluating nutritional needs
- Pediatric medicine and oncology dosing
Understanding your BSA can help improve treatment accuracy and safety.
How to Use the BSA Calculator
Using our BSA Calculator is simple and user-friendly:
- Enter Your Weight: Input your weight in kilograms in the designated field. The calculator allows decimal inputs for precise measurement.
- Enter Your Height: Input your height in centimeters. Accurate height data ensures correct BSA results.
- Calculate BSA: Click the Calculate button. The calculator automatically computes your Body Surface Area using a standard formula.
- View Results: Your BSA is displayed in square meters (m²) immediately below the input fields.
- Reset if Needed: Use the Reset button to clear the fields and enter new values.
This tool eliminates manual calculations and ensures fast and reliable results, perfect for both healthcare professionals and general users.
Example Calculation
Suppose you weigh 70 kg and your height is 175 cm.
Using the BSA formula: BSA=Height(cm)×Weight(kg)3600BSA = \sqrt{\frac{Height(cm) \times Weight(kg)}{3600}}BSA=3600Height(cm)×Weight(kg)
Step-by-step:
- Multiply height by weight: 175 × 70 = 12,250
- Divide by 3600: 12,250 ÷ 3600 ≈ 3.40
- Take the square root: √3.40 ≈ 1.84 m²
Your BSA is 1.84 m², which is typical for an adult of average height and weight.
Benefits of Using the BSA Calculator

Why BSA is Important
BSA is preferred over body weight alone for certain medical calculations because:
- Medication Dosage: Many drugs, especially chemotherapy agents, are dosed based on BSA.
- Fluid Management: Helps estimate fluid replacement in hospitals.
- Pediatric Care: Ensures correct dosing for children where weight alone might not be enough.
- Body Composition Analysis: Assists in nutritional and metabolic studies.
By knowing your BSA, you ensure treatments are safer, more effective, and personalized to your body’s needs.
