What Is the Body Surface Area Mosteller Calculator?
Body Surface Area (BSA) is the measured or calculated surface area of a human body, expressed in square meters.
How Does the Body Surface Area Mosteller Calculator Work?
The Mosteller equation takes the square root of height in centimeters multiplied by weight in kilograms divided by 3,600.
Body Surface Area Mosteller Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
BSA (m²) = √[(Height (cm) × Weight (kg)) ÷ 3,600]
Multiplies height by weight, divides by 3600, and takes the square root to yield total body surface area in square meters.
How to Use the Body Surface Area Mosteller Calculator
- Enter your measured height in cm and current weight in kg to immediately receive your BSA score and demographic comparison.
Step-by-Step Example Calculation
Adult (175 cm, 70 kg)
Input Values:
heightCm:175
weightKg:70
Understanding Your Result
Results between 1.6 m² and 2.0 m² represent normal adult ranges, with 1.73 m² serving as the standard reference benchmark.
Factors That Affect the Result
- Skeletal stature, limb length, and overall body adiposity.
When Should You Use This Calculator?
- Calculating oncology pharmacotherapy doses, adjusting cardiac output indexes, and evaluating burn surface percentages.
Assumptions & Limitations
- Extremely unusual body proportions (severe amputations or morbid obesity) may require specialized adjusted metrics.
