How many units is 500 mcg from a 10 mg vial with 1 mL of water?
10 mg ÷ 1 mL = 10 mg/mL (10000 mcg/mL). 500 mcg ÷ 10000 mcg/mL = 0.05 mL. On a U-100 syringe that is 5 units (U-50: 2.5, U-40: 2). The vial holds 20 draws of that size.
The math
Concentration = 10 mg ÷ 1 mL = 10 mg/mL Volume = 500 mcg ÷ 10000 mcg/mL = 0.05 mL Units (U-100) = 0.05 × 100 = 5

Draw to
5 units
= 0.05 mL · concentration 10 mg/mL (10000 mcg/mL) · 20 draws per vial
Concentration = 10 mg ÷ 1 mL = 10 mg/mL Volume = 500 mcg ÷ 10000 mcg/mL = 0.05 mL Units = 0.05 mL × 100 (U-100) = 5 units
