Vial to Units

15 units to mL

15 units is 0.15 mL on a U-100 insulin syringe. 100 units is 1 mL, so divide units by 100. 0.15 mL is also 0.15 cc.

15 units on different syringes

Units are a marking, not a fixed volume. The volume depends on the syringe type printed on the barrel.

Questions

How many mL is 15 units?

0.15 mL on a U-100 insulin syringe. 100 units is 1 mL, so divide units by 100.

Is 15 units the same volume on every syringe?

No. On a U-100 syringe 15 units is 0.15 mL. On a U-40 syringe, where 40 units is 1 mL, 15 units is 0.375 mL. Check which type is printed on the barrel.

How many cc is 15 units?

0.15 cc. A cc and a mL are the same volume.

How many mg is 15 units?

That depends on the concentration of the liquid. 0.15 mL holds 0.75 mg at 5 mg/mL and 1.5 mg at 10 mg/mL.

Which insulin syringe holds 15 units?

Any U-100 syringe with a capacity of 15 units 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 15 units to mg.
