On a standard U-100 insulin syringe, 100 units = 1 mL, so 1 unit = 0.01 mL. This holds on all U-100 syringes; the 30/50/100 label is the maximum volume.
| Units | Millilitres |
|---|---|
| 5 U | 0.05 mL |
| 10 U | 0.10 mL |
| 20 U | 0.20 mL |
| 30 U | 0.30 mL |
| 50 U | 0.50 mL |
| 100 U | 1.00 mL |
| Syringe | Max volume | Max units |
|---|---|---|
| U-30 | 0.3 mL | 30 U |
| U-50 | 0.5 mL | 50 U |
| U-100 | 1.0 mL | 100 U |
