8 units to mg
8 units on a U-100 insulin syringe is 0.08 mL. That holds 0.4 mg when the vial is 5 mg/mL and 0.8 mg at 10 mg/mL. mg = units ÷ 100 × mg/mL.
8 units in mg, by concentration
| Concentration | Volume | 8 units = |
|---|---|---|
| 1 mg/mL · 5 mg vial + 5 mL | 0.08 mL | 0.08 mg · 80 mcg |
| 2 mg/mL · 10 mg vial + 5 mL | 0.08 mL | 0.16 mg · 160 mcg |
| 2.5 mg/mL · 5 mg vial + 2 mL | 0.08 mL | 0.2 mg · 200 mcg |
| 3 mg/mL · 15 mg vial + 5 mL | 0.08 mL | 0.24 mg · 240 mcg |
| 5 mg/mL · 10 mg vial + 2 mL | 0.08 mL | 0.4 mg · 400 mcg |
| 7.5 mg/mL · 15 mg vial + 2 mL | 0.08 mL | 0.6 mg · 600 mcg |
| 10 mg/mL · 10 mg vial + 1 mL | 0.08 mL | 0.8 mg · 800 mcg |
| 15 mg/mL · 30 mg vial + 2 mL | 0.08 mL | 1.2 mg |
| 20 mg/mL · 20 mg vial + 1 mL | 0.08 mL | 1.6 mg |

Questions
How many mg is 8 units?
8 units on a U-100 syringe is 0.08 mL. Multiply that by the concentration: at 5 mg/mL it is 0.4 mg, at 10 mg/mL it is 0.8 mg.
How many mL is 8 units?
0.08 mL. On a U-100 insulin syringe 100 units is 1 mL.
How many mcg is 8 units?
Work out the mg first, then multiply by 1,000. At 5 mg/mL, 8 units is 0.4 mg, which is 400 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.
