How the math works
- Concentration = vial size (mg) ÷ diluent volume (mL). Example: 10 mg in 2 mL = 5 mg/mL.
- Volume per dose (mL) = target dose (mg) ÷ concentration (mg/mL).
- Syringe units = volume (mL) × 100. Standard U-100 insulin syringes read 100 units per 1 mL — so 0.25 mL = 25 units. Pick the smallest syringe size your dose fits in (0.3 / 0.5 / 1.0 mL).
- Doses per vial = vial size (mg) ÷ dose (mg).
