Vial to Units

25 units to mL

25 units is 0.25 mL on a U-100 insulin syringe. 100 units is 1 mL, so divide units by 100. 0.25 mL is also 0.25 cc.

25 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 25 units?

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

Is 25 units the same volume on every syringe?

No. On a U-100 syringe 25 units is 0.25 mL. On a U-40 syringe, where 40 units is 1 mL, 25 units is 0.625 mL. Check which type is printed on the barrel.

How many cc is 25 units?

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

How many mg is 25 units?

That depends on the concentration of the liquid. 0.25 mL holds 1.25 mg at 5 mg/mL and 2.5 mg at 10 mg/mL.

Which insulin syringe holds 25 units?

Any U-100 syringe with a capacity of 25 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.
