Enter the total dosage in milligrams (mg) and the number of hours over which the medication should be administered into the calculator to determine the mg per hour dosage rate.

Mg Per Hour Formula

The following formula is used to calculate the mg per hour dosage rate.

mg/hour = Total Dosage (mg) / Hours

Variables:

  • Total Dosage (mg) is the total amount of medication prescribed in milligrams.
  • Hours is the time period over which the medication should be administered.

To calculate the mg per hour dosage rate, divide the total dosage in milligrams by the number of hours over which the medication should be administered.

What is Mg Per Hour Dosage Rate?

The mg per hour dosage rate is a measure of how much medication is administered over one hour. This is commonly used in medical settings to ensure a patient receives a consistent amount of medication throughout a specified time period. It is particularly important for medications that need to be dosed at a steady rate to maintain therapeutic levels in the bloodstream.

How to Calculate Mg Per Hour?

The following steps outline how to calculate the mg per hour dosage rate.


  1. First, determine the total dosage prescribed (in milligrams).
  2. Next, determine the number of hours over which the medication should be administered.
  3. Use the formula: mg/hour = Total Dosage (mg) / Hours.
  4. Finally, calculate the mg per hour dosage rate.
  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.

Total Dosage (mg) = 600 mg

Hours = 12 hours
