To calculate your body surface area (BSA) using the Mosteller formula, simply enter your weight in kilograms and height in centimeters into the calculator above. The Mosteller formula is widely used in clinical settings to estimate the body surface area of patients, which is crucial for determining dosages for medications, especially in chemotherapy.

Understanding Body Surface Area

Body surface area is a measure of the total surface area of the human body. It is an important parameter in medicine, particularly in pharmacology and oncology, as it helps in calculating the appropriate dosages of drugs. The Mosteller formula is one of the simplest and most commonly used methods to estimate BSA.

The Mosteller Formula

The Mosteller formula for calculating body surface area is:

BSA (m²) = √((Weight (kg) × Height (cm)) / 3600)

This formula provides a quick and easy way to estimate BSA without the need for complex calculations or equipment. It is particularly useful in clinical settings where time is of the essence.

Why is BSA Important?

Body surface area is crucial for several reasons:

  • It helps in determining the correct dosage of medications, especially in chemotherapy, where the dose is often calculated based on BSA.
  • BSA is used in various medical calculations, including cardiac output and metabolic rate.
  • It provides a more accurate measure of body size than weight alone, especially in individuals with higher or lower than average body fat.

How to Use the BSA Calculator

Using the BSA calculator is straightforward:

  1. Enter your weight in kilograms.
  2. Enter your height in centimeters.
  3. Click on the “Calculate” button to get your body surface area.
  4. If you need to start over, click the “Reset” button.

Example Calculation

For instance, if a person weighs 70 kg and is 175 cm tall, the calculation would be:

BSA = √((70 kg × 175 cm) / 3600) ≈ 1.84 m²
