mg to mL Calculator
Free Mgtom lcalculator Converter for volume & weight units. Enter a value to see equivalent measurements across systems.
Formula
Volume (mL) = Mass (mg) / Concentration (mg/mL)
Divide the desired dose in milligrams by the solution concentration in mg/mL to get the required volume in milliliters. The concentration tells you how much active ingredient is in each mL of liquid.
Worked Examples
Example 1: Liquid Medication Dosing
Problem: A doctor prescribes 400 mg of ibuprofen. The liquid form is 100 mg/5 mL (20 mg/mL). How many mL?
Solution: Volume = Dose / Concentration\nVolume = 400 mg / 20 mg/mL = 20 mL\nTeaspoons = 20 / 4.93 = 4.06 tsp
Result: 400 mg = 20 mL at 20 mg/mL concentration
Example 2: IV Drip Calculation
Problem: An IV bag has 250 mL of solution at 2 mg/mL concentration. What is the total drug content?
Solution: Total mg = Volume x Concentration\nTotal mg = 250 mL x 2 mg/mL = 500 mg\nGrams = 500 / 1000 = 0.5 g
Result: 250 mL at 2 mg/mL = 500 mg total
