How It Works
1. Concentration
Divide vial amount (mcg) by water volume (mL) to get concentration (mcg/mL).
2. Volume needed
Divide desired dose by concentration to get injection volume in mL.
3. Syringe units
Multiply mL × 100 to get U-100 syringe units (IU).
Example
- 5 mg vial + 2 mL water = 2.5 mg/mL
- Want 250 mcg (0.25 mg)?
- 0.25 ÷ 2.5 = 0.1 mL
- 0.1 mL = 10 units on a U-100 syringe
