BSA Calculator – Body Surface Area







 

Introduction

Calculating the Body Surface Area (BSA) is important for various medical and clinical purposes. BSA is a crucial metric used in determining medication dosages, assessing skin burns, and evaluating the nutritional status of an individual. The Mosteller Method provides a simple and reliable way to estimate BSA using just the height and weight of a person. In this article, we’ll guide you through how to use this online Body Surface Area Calculator, explain the formula behind it, provide an example, answer some frequently asked questions, and offer a conclusion.

How to Use

Using the Body Surface Area Calculator (Mosteller Method) is a straightforward process:

  1. Enter your height in centimeters in the “Height” field.
  2. Enter your weight in kilograms in the “Weight” field.
  3. Click the “Calculate” button.

The calculator will instantly compute your Body Surface Area in square meters and display the result.

Formula

The Mosteller Method formula to calculate Body Surface Area (BSA) is as follows:

BSA (m²) = (√(height (cm) x weight (kg)/3600))

Where:

  • BSA (m²) is the Body Surface Area in square meters.
  • Height (cm) is the height of the individual in centimeters.
  • Weight (kg) is the weight of the individual in kilograms.

Example

Let’s consider an example: a person with a height of 170 cm and a weight of 70 kg wants to calculate their Body Surface Area.

  1. Enter the height (170 cm) and weight (70 kg) into the calculator.
  2. Click the “Calculate” button.

The calculator will use the Mosteller Method formula to determine the BSA:

BSA (m²) = (√(170 cm x 70 kg / 3600)) ≈ 1.85 m²

So, the person’s Body Surface Area is approximately 1.85 square meters.

FAQ’s

Q1: Why is calculating Body Surface Area important?

Calculating BSA is essential for determining medication dosages, evaluating nutritional requirements, and assessing skin burns. It helps healthcare professionals make informed decisions about treatment and care.

Q2: Are there other methods to calculate BSA?

Yes, apart from the Mosteller Method, there are other methods like the Dubois Method, Haycock Formula, and Gehan and George Equation. Each method uses slightly different formulas, but Mosteller’s formula is widely accepted for its simplicity and accuracy.

Q3: Is this calculator suitable for children and adults?

Yes, the calculator is suitable for both children and adults. It works based on the input of height and weight, making it applicable for a wide range of ages.

Conclusion

Calculating Body Surface Area using the Mosteller Method is crucial in various medical and clinical scenarios. This online Body Surface Area Calculator simplifies the process by providing an efficient tool to determine BSA quickly and accurately. Whether you’re a healthcare professional or an individual looking to assess your BSA, this calculator offers a user-friendly and reliable solution.
