15 Units to mg (U-100 Insulin Syringe)
15 units on a U-100 insulin syringe is 0.15 mL. How many mg that is depends on the vial: with a 5 mg vial mixed in 2 mL it is 375 mcg; with a 10 mg vial in 2 mL it is 750 mcg.

FAQ
How many mg is 15 units?
+
15 units on a U-100 insulin syringe is 0.15 mL. How many mg that is depends on the vial: with a 5 mg vial mixed in 2 mL it is 375 mcg; with a 10 mg vial in 2 mL it is 750 mcg.
How many mL is 15 units?
+
On a U-100 insulin syringe, 100 units = 1 mL, so 15 units = 0.15 mL. That holds for any liquid; only the amount of drug in it changes with concentration.
Is 15 units the same as 15 mg?
+
No. Units measure volume on the syringe; mg measures the amount of peptide. They only line up at one specific concentration (10 mg/mL makes 1 unit = 0.1 mg). Always convert using your own vial and water volume.
