40 units to mL
40 units is 0.4 mL on a U-100 insulin syringe. 100 units is 1 mL, so divide units by 100. 0.4 mL is also 0.4 cc.
40 units on different syringes
Units are a marking, not a fixed volume. The volume depends on the syringe type printed on the barrel.
| Syringe | 40 units = | Capacity |
|---|---|---|
| U-100, 0.3 mL barrel · 30 units | 0.4 mL | Does not fit |
| U-100, 0.5 mL barrel · 50 units | 0.4 mL | Fits |
| U-100, 1 mL barrel · 100 units | 0.4 mL | Fits |
| U-40 · 40 units = 1 mL | 1 mL | Different scale |

Questions
How many mL is 40 units?
0.4 mL on a U-100 insulin syringe. 100 units is 1 mL, so divide units by 100.
Is 40 units the same volume on every syringe?
No. On a U-100 syringe 40 units is 0.4 mL. On a U-40 syringe, where 40 units is 1 mL, 40 units is 1 mL. Check which type is printed on the barrel.
How many cc is 40 units?
0.4 cc. A cc and a mL are the same volume.
How many mg is 40 units?
That depends on the concentration of the liquid. 0.4 mL holds 2 mg at 5 mg/mL and 4 mg at 10 mg/mL.
Which insulin syringe holds 40 units?
Any U-100 syringe with a capacity of 40 units or more. The smallest standard barrel that fits is 0.5 mL (50 units). Smaller barrels have wider spacing between marks, which makes them easier to read.
For the amount at each concentration, see 40 units to mg.
