What is the total volume of your syringe?
This sets the units scale. For U-100 insulin syringes, 1 mL = 100 units.

How to Use This Calculator
Enter your vial amount, bacteriostatic water volume, and target dose in mcg. The calculator uses these inputs to calculate concentration and the syringe units needed for the dose.
All values are based on your inputs and standard unit conversions, and the output represents the approximate volume to draw.

Example Calculation
Example: A 10 mg vial reconstituted with 2 mL yields a concentration of 5,000 mcg/mL. A 250 mcg target dose would equal 0.05 mL, which corresponds to 5 units on a U-100 syringe. This is a mathematical example only and not medical advice.
