0.25 mL to units
0.25 mL is 25 units on a U-100 insulin syringe. 1 mL is 100 units, so multiply mL by 100. 0.25 mL is the same as 0.25 cc.
0.25 mL on different syringes
| Syringe | 0.25 mL = | Capacity |
|---|---|---|
| U-100, 0.3 mL barrel · 30 units | 25 units | Fits |
| U-100, 0.5 mL barrel · 50 units | 25 units | Fits |
| U-100, 1 mL barrel · 100 units | 25 units | Fits |
| U-40 · 40 units = 1 mL | 10 units | Different scale |
How much of the vial 0.25 mL is
A draw of 0.25 mL (25 units) takes a fixed share of the liquid in the vial. The share depends only on how much water was added. The last two columns apply that share to a 5 mg and a 10 mg vial.
| Water added | Share of vial | From a 5 mg vial | From a 10 mg vial |
|---|---|---|---|
| 1 mL | 25% | 1.25 mg | 2.5 mg |
| 2 mL | 12.5% | 0.625 mg · 625 mcg | 1.25 mg |
| 3 mL | 8.333% | 0.4167 mg · 416.7 mcg | 0.8333 mg · 833.3 mcg |
| 5 mL | 5% | 0.25 mg · 250 mcg | 0.5 mg · 500 mcg |

Questions
How many units is 0.25 mL?
25 units on a U-100 insulin syringe. 1 mL is 100 units, so multiply mL by 100.
Is 0.25 mL the same as 0.25 cc?
Yes. A cc and a mL are the same volume, so 0.25 cc is also 25 units on a U-100 syringe.
How many units is 0.25 mL on a U-40 syringe?
10 units. A U-40 syringe is marked so that 40 units is 1 mL, so the same volume reads as a smaller number than on a U-100 syringe.
How many mg is in 0.25 mL?
Multiply 0.25 mL by the concentration in mg/mL. At 5 mg/mL it is 1.25 mg; at 10 mg/mL it is 2.5 mg.
How much of a vial is 0.25 mL?
Divide 0.25 by the mL of water added. If 2 mL was added, 0.25 mL is 12.5% of the vial.
