The Units/Hr to mL/Hr Calculator is designed to convert the amount of medication prescribed in units per hour to the volume in milliliters per hour. This calculation is crucial for the proper setting of infusion pumps which, unlike syringes or pens, require a volume for dosing instead of a unit count. Understanding this conversion helps in achieving precise control over the medication dosage administered to patients, which can be life-saving.
Formula of Units/Hr To Ml/Hr Calculator
Understanding the Formula:
This formula helps convert the dosage of medication from units per hour (as commonly prescribed in medications like insulin) to milliliters per hour (used by infusion pumps). The formula involves two primary variables:
- Dosage: This is the amount of medication prescribed, measured in units per hour.
- Concentration: This represents the number of units of medication contained in one milliliter of solution.
How to Apply the Formula:
To use the formula, simply divide the prescribed dosage (in units/hr) by the concentration (units/mL). The result will give you the flow rate in milliliters per hour, which can be set on the infusion pump.
Helpful Conversion Table
For ease of use, below is a table with common dosages and concentrations, along with the calculated mL/hr output:
| Dosage (units/hr) | Concentration (units/mL) | Result (mL/hr) |
|---|---|---|
| 50 | 100 | 0.5 |
| 100 | 50 | 2.0 |
| 30 | 10 | 3.0 |
| 75 | 25 | 3.0 |
This table serves as a quick reference to avoid manual calculations, ensuring quick and error-free medication setup.
Example of Units/Hr To Ml/Hr Calculator
Consider a patient who is prescribe 60 units of insulin per hour. The insulin concentration available is 20 units/mL. Using our formula:
Result (mL/hr) = 60 units/hr / 20 units/mL = 3 mL/hr
This means to administer 60 units of insulin per hour, you would set the infusion pump to deliver 3 mL of insulin per hour.
Most Common FAQs
Adjust the concentration variable in the formula accordingly. Always ensure you have the correct concentration to maintain dosing accuracy.
Always double-check your calculations. If possible, use digital tools like calculators or apps designed for medical conversions to verify your results.
Yes, several mobile apps and online calculators are available that can automatically perform these conversions to minimize errors and simplify the process.
