Enter the dosage in units per hour and the concentration in units per milliliter into the calculator to convert the dosage to milliliters per hour. This calculator helps in determining the infusion rate for medications.

Units/Hr to mL/Hr Conversion Formula

The following formula is used to convert a dosage from units per hour to milliliters per hour.

Result (mL/hr) = Dosage (units/hr) / Concentration (units/mL)

Variables:

  • Dosage is the prescribed amount of medication in units per hour.
  • Concentration is the amount of medication per milliliter of solution.

To convert the dosage to milliliters per hour, divide the dosage in units per hour by the concentration in units per milliliter.

What is Dosage Conversion?

Dosage conversion is the process of converting the amount of medication prescribed in units (such as insulin units) to the volume to be administered in milliliters. This is particularly important for medications that are delivered intravenously or subcutaneously, where precise volumes need to be administered at specific rates.

How to Calculate Dosage Conversion?

The following steps outline how to calculate the dosage conversion from units per hour to milliliters per hour.


  1. First, determine the prescribed dosage in units per hour.
  2. Next, determine the concentration of the medication in units per milliliter.
  3. Use the formula: Result (mL/hr) = Dosage (units/hr) / Concentration (units/mL).
  4. Finally, calculate the result in milliliters per hour.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

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

Dosage (units/hr) = 50 units per hour

Concentration (units/mL) = 100 units per milliliter
