1 unit to mL
1 unit is 0.01 mL on a U-100 insulin syringe. 100 units is 1 mL, so divide units by 100. 0.01 mL is also 0.01 cc.
1 unit on different syringes
Units are a marking, not a fixed volume. The volume depends on the syringe type printed on the barrel.
| Syringe | 1 unit = | Capacity |
|---|---|---|
| U-100, 0.3 mL barrel · 30 units | 0.01 mL | Fits |
| U-100, 0.5 mL barrel · 50 units | 0.01 mL | Fits |
| U-100, 1 mL barrel · 100 units | 0.01 mL | Fits |
| U-40 · 40 units = 1 mL | 0.025 mL | Different scale |
Units to mL around 1 unit
| Units | mL on a U-100 syringe | mL on a U-40 syringe |

| 2 units | 0.02 mL | 0.05 mL |
| 5 units | 0.05 mL | 0.125 mL |
| 10 units | 0.1 mL | 0.25 mL |

Questions
How many mL is 1 unit?
0.01 mL on a U-100 insulin syringe. 100 units is 1 mL, so divide units by 100.
Is 1 unit the same volume on every syringe?
No. On a U-100 syringe 1 unit is 0.01 mL. On a U-40 syringe, where 40 units is 1 mL, 1 unit is 0.025 mL. Check which type is printed on the barrel.
How many cc is 1 unit?
0.01 cc. A cc and a mL are the same volume.
How many mg is 1 unit?
That depends on the concentration of the liquid. 0.01 mL holds 0.05 mg at 5 mg/mL and 0.1 mg at 10 mg/mL.
Which insulin syringe holds 1 unit?
Any U-100 syringe with a capacity of 1 unit or more. The smallest standard barrel that fits is 0.3 mL (30 units). Smaller barrels have wider spacing between marks, which makes them easier to read.
For the amount at each concentration, see 1 unit to mg.
