How many units is 2000 mcg from a 20 mg vial with 2 mL of water?
20 mg ÷ 2 mL = 10 mg/mL (10000 mcg/mL). 2000 mcg ÷ 10000 mcg/mL = 0.2 mL. On a U-100 syringe that is 20 units (U-50: 10, U-40: 8). The vial holds 10 draws of that size.
The math
Concentration = 20 mg ÷ 2 mL = 10 mg/mL Volume = 2000 mcg ÷ 10000 mcg/mL = 0.2 mL Units (U-100) = 0.2 × 100 = 20

Draw to
20 units
= 0.2 mL · concentration 10 mg/mL (10000 mcg/mL) · 10 draws per vial
Concentration = 20 mg ÷ 2 mL = 10 mg/mL Volume = 2000 mcg ÷ 10000 mcg/mL = 0.2 mL Units = 0.2 mL × 100 (U-100) = 20 units
