FAQ
How many units is 250 mcg?
+
0.25 mg = 250 mcg. Units depend on concentration: with a 5 mg vial mixed in 2 mL of bacteriostatic water, 250 mcg is 10 units (0.1 mL) on a U-100 syringe.
How many units is 250 mcg with a 5 mg vial vs a 10 mg vial?
+
Mixed with 2 mL of water: a 5 mg vial gives 10 units, a 10 mg vial gives 5 units. A stronger vial means fewer units for the same dose.
How do I calculate 250 mcg in units myself?
+
Concentration = vial mg × 1,000 ÷ water mL (in mcg per mL). Volume = 250 mcg ÷ concentration. Units = volume × 100 on a U-100 syringe.
