Body Surface Area (BSA) Calculator
Calculate Body Surface Area using Mosteller and DuBois formulas.
Mathematical Formula
Mosteller BSA (m²) = sqrt((weight (kg) * height (cm)) / 3600)
Overview & Explanation
Body Surface Area (BSA) measures the total surface area of the human body, applied in clinical dosage calculations.
How It Works
- Multiplies weight by height.
- Divides by 3600.
- Takes the square root.
Practical Applications
- Clinical drug dosage.
- Cardiac index calculation.
70 kg and 175 cm BSA
Calculate BSA using Mosteller formula.
1
Multiply weight by height
70 * 175
= 12250
2
Divide by 3600 and take square root
sqrt(12250 / 3600)
= 1.84 m²
Frequently Asked Questions
