Unit conversion · U-100 insulin syringe

Mcg to units chart.

Units on a U-100 syringe equal the amount in micrograms divided by the micrograms per unit of your mix. At 2.5 mg/mL (5 mg in 2 mL) each unit holds 25 mcg, so 250 mcg is 10 units.

Units for common amounts, by concentration

Find the amount down the side and your concentration across the top. Cells over 100 units exceed a 1 mL syringe. This converts amounts; it does not suggest any.
