Enter the dosage in mg/hr and the concentration in mg/ml into the calculator to convert the dosage to ml/hr. This calculator helps in determining the flow rate for medical infusions.

Mg/Hr to Ml/Hr Conversion Formula

The following formula is used to convert a dosage from mg/hr to ml/hr.

Flow rate (ml/hr) = Dosage (mg/hr) / Concentration (mg/ml)

Variables:

  • Dosage is the prescribed amount of medication in milligrams per hour (mg/hr)
  • Concentration is the concentration of the medication in milligrams per milliliter (mg/ml)

To convert a dosage from mg/hr to ml/hr, divide the dosage by the concentration.

What is Dosage Conversion?

Dosage conversion is the process of converting the amount of medication prescribed in milligrams per hour to the volume that should be administered in milliliters per hour. This is a common calculation in the medical field, especially for nurses and pharmacists who prepare and administer intravenous medications. The conversion is necessary to ensure that patients receive the correct amount of medication according to the prescribed dosage and concentration.

How to Calculate Dosage Conversion?

The following steps outline how to calculate the dosage conversion from mg/hr to ml/hr.


  1. First, determine the prescribed dosage in milligrams per hour (mg/hr).
  2. Next, determine the concentration of the medication in milligrams per milliliter (mg/ml).
  3. Use the formula from above to calculate the flow rate in milliliters per hour (ml/hr).
  4. Finally, enter the values into the calculator to verify the result.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Prescribed dosage (mg/hr) = 50 mg/hr

Medication concentration (mg/ml) = 2 mg/ml
