Calculate Meter Squared Body Surface Area
Introduction & Importance
Body surface area (BSA) is a critical parameter in medicine, pharmacology, and physiology. It’s calculated in square meters and is used to normalize various physiological parameters, such as drug dosing, nutrition, and fluid requirements.
BSA is calculated using the Mosteller formula, which is based on height and weight. Here, we’ll calculate the body surface area in square meters (m2).
How to Use This Calculator
- Enter your height in centimeters (cm) and weight in kilograms (kg).
- Click the “Calculate” button.

Formula & Methodology
The Mosteller formula for calculating BSA is:
BSA (m2) = (Height (cm) x Weight (kg)) / 3600
Real-World Examples
Case Study 1
A 175 cm tall, 70 kg individual would have a BSA of:
BSA = (175 x 70) / 3600 = 1.93 m2
Data & Statistics
| Age (years) | Male (m2) | Female (m2) |
|---|---|---|
| 20 | 1.9 | 1.6 |
| Height (cm) | Weight (kg) | Mosteller (m2) | Du Bois (m2) |
|---|---|---|---|
| 175 | 70 | 1.93 | 1.89 |
Expert Tips
- Always use the Mosteller formula for BSA calculation.
- Accurate height and weight measurements are crucial for precise BSA calculation.
- BSA is used in various clinical settings, including pharmacokinetics, nutrition, and fluid management.
