50 units to mg
50 units on a U-100 insulin syringe is 0.5 mL. That holds 2.5 mg when the vial is 5 mg/mL and 5 mg at 10 mg/mL. mg = units ÷ 100 × mg/mL.
50 units in mg, by concentration
| Concentration | Volume | 50 units = |
|---|---|---|
| 1 mg/mL · 5 mg vial + 5 mL | 0.5 mL | 0.5 mg · 500 mcg |
| 2 mg/mL · 10 mg vial + 5 mL | 0.5 mL | 1 mg |
| 2.5 mg/mL · 5 mg vial + 2 mL | 0.5 mL | 1.25 mg |
| 3 mg/mL · 15 mg vial + 5 mL | 0.5 mL | 1.5 mg |
| 5 mg/mL · 10 mg vial + 2 mL | 0.5 mL | 2.5 mg |
| 7.5 mg/mL · 15 mg vial + 2 mL | 0.5 mL | 3.75 mg |
| 10 mg/mL · 10 mg vial + 1 mL | 0.5 mL | 5 mg |
| 15 mg/mL · 30 mg vial + 2 mL | 0.5 mL | 7.5 mg |
| 20 mg/mL · 20 mg vial + 1 mL | 0.5 mL | 10 mg |

Questions
How many mg is 50 units?
50 units on a U-100 syringe is 0.5 mL. Multiply that by the concentration: at 5 mg/mL it is 2.5 mg, at 10 mg/mL it is 5 mg.
How many mL is 50 units?
0.5 mL. On a U-100 insulin syringe 100 units is 1 mL.
How many mcg is 50 units?
Work out the mg first, then multiply by 1,000. At 5 mg/mL, 50 units is 2.5 mg, which is 2,500 mcg.
How do I find the concentration of my vial?
Divide the mg printed on the vial by the mL of water that was added. A 10 mg vial with 2 mL added is 5 mg/mL. If the vial was dispensed as a liquid, the mg/mL is printed on the label.
