How many units is 0.5 mL?
0.5 mL is 50 units on a U-100 syringe, 25 units on U-50 and 20 units on U-40. It fills a 0.5 mL U-100 syringe exactly, or half of a 1 mL U-100 syringe.
The math
U-100: 0.5 × 100 = 50 units U-50: 0.5 × 50 = 25 units U-40: 0.5 × 40 = 20 units

10 units
= 0.1 mL · concentration 2.5 mg/mL (2500 mcg/mL) · 20 draws per vial
Concentration = 5 mg ÷ 2 mL = 2.5 mg/mL Volume = 250 mcg ÷ 2500 mcg/mL = 0.1 mL Units = 0.1 mL × 100 (U-100) = 10 units
