How many units is 3 mg with a 5 mg vial vs a 10 mg vial?
+
Mixed with 2 mL of water: a 5 mg vial gives 120 units, a 10 mg vial gives 60 units. A stronger vial means fewer units for the same dose.
How do I calculate 3 mg in units myself?
+
Concentration = vial mg × 1,000 ÷ water mL (in mcg per mL). Volume = 3,000 mcg ÷ concentration. Units = volume × 100 on a U-100 syringe.
