Height_cmStature height in centimeters
Weight_kgBody mass weight in kilograms

How to Use the Body Surface Area (BSA) Calculator

  • Enter height in inches or centimeters.
  • Enter weight in pounds or kilograms.
  • Calculate BSA in square meters (m²) across Mosteller, DuBois, and Haycock equations.

Practical Example Calculation

Scenario Context: 175 cm tall individual weighing 70 kg.

Step 1: Multiply height and weight: 175 * 70 = 12,250.
Step 2: Divide by 3,600 = 3.4028.
Step 3: Square root: sqrt(3.4028) = 1.84 m².
Calculated BSA: 1.84 m².
