Mg/M2 Dose Calculator



In the realm of healthcare, precise medication dosages are of paramount importance. Calculating the correct dose based on a patient’s weight and height can be a complex task. To streamline this process, we introduce the Mg/M2 Dose Calculator, a valuable tool for healthcare professionals. This calculator utilizes a straightforward formula to determine the accurate medication dosage in milligrams per square meter (mg/m2), ensuring patients receive the appropriate treatment. In this guide, we will delve into how to use the calculator, the underlying formula, provide a practical example, address frequently asked questions, and conclude with a comprehensive understanding of this essential tool.

How to Use 

Using the Mg/M2 Dose Calculator is a simple and efficient process. Follow these steps:

  1. Input Medication Dosage (mg): Enter the prescribed medication dosage in milligrams.
  2. Input Weight (kg): Input the patient’s weight in kilograms.
  3. Input Height (cm): Input the patient’s height in centimeters.
  4. Click Calculate: Press the “Calculate” button to instantly obtain the dosage in mg/m2.


The formula for calculating medication dosage in mg/m2 is as follows:

D = (M * SQRT(W * H / 3600))


  • D represents the medication dosage in mg/m2.
  • M is the prescribed medication dosage in milligrams.
  • W is the patient’s weight in kilograms.
  • H is the patient’s height in centimeters.


Let’s calculate the medication dosage in mg/m2 using the formula for a patient with a prescribed medication dosage of 200 mg, a weight of 70 kg, and a height of 160 cm:

D = (200 * SQRT(70 * 160 / 3600))

D = (200 * SQRT(11200 / 3600))

D ≈ (200 * 10.58)

D ≈ 2116.18 mg/m2

So, the calculated dosage for this patient is approximately 2116.18 mg/m2.
