Dosage Volume Formula:
From: | To: |
Definition: This calculator converts medication dosage from milligrams (mg) to milliliters (ml) based on the concentration of the solution.
Purpose: It helps healthcare professionals and patients accurately measure liquid medications when the prescribed dose is in milligrams but the medication is in liquid form.
The calculator uses the formula:
Where:
Explanation: The desired dose is divided by the concentration to determine the volume needed to achieve that dose.
Details: Proper dosage calculation ensures patient safety, prevents underdosing or overdosing, and ensures effective treatment.
Tips: Enter the desired dose in milligrams and the medication concentration in mg/ml. Both values must be greater than 0.
Q1: Where do I find the concentration of my medication?
A: The concentration is typically listed on the medication label (e.g., 250 mg/5ml) or in the prescribing information.
Q2: What if my medication concentration is in a different unit?
A: Convert all units to consistent measurements (mg and ml) before using the calculator.
Q3: How precise should my measurements be?
A: For critical medications, measure to the nearest 0.1 ml using an appropriate syringe.
Q4: Does this work for all liquid medications?
A: Yes, as long as you know the exact concentration of the medication in mg/ml.
Q5: What if I need to calculate for a child's weight-based dose?
A: First calculate the desired dose in mg based on weight (mg/kg), then use this calculator to convert to ml.
