50 Units to mg (U-100 Insulin Syringe)
50 units on a U-100 insulin syringe is 0.5 mL. How many mg that is depends on the vial: with a 5 mg vial mixed in 2 mL it is 1.25 mg; with a 10 mg vial in 2 mL it is 2.5 mg.

FAQ
How many mg is 50 units?
+
50 units on a U-100 insulin syringe is 0.5 mL. How many mg that is depends on the vial: with a 5 mg vial mixed in 2 mL it is 1.25 mg; with a 10 mg vial in 2 mL it is 2.5 mg.
How many mL is 50 units?
+
On a U-100 insulin syringe, 100 units = 1 mL, so 50 units = 0.5 mL. That holds for any liquid; only the amount of drug in it changes with concentration.
Is 50 units the same as 50 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.
