Quick reference chart
On a U-100 syringe, 100 units = 1 mL. The units for a dose depend on your vial's concentration:
| Dose | At 5 mg/mL | At 10 mg/mL |
|---|---|---|
| 2.5 mg | 50 units | 25 units |
| 5 mg | 100 units | 50 units |
| 7.5 mg | 150 units (over 1 mL) | 75 units |
| 10 mg | 200 units (over 1 mL) | 100 units |
| 12.5 mg | 250 units (over 1 mL) | 125 units (over 1 mL) |
| 15 mg | 300 units (over 1 mL) | 150 units (over 1 mL) |
The formula
units = (dose mg ÷ concentration mg/mL) × 100
Example: 2.5 mg ÷ 10 mg/mL × 100 = 25 units.
