Vial to Units

0.3 mL to units

0.3 mL is 30 units on a U-100 insulin syringe. 1 mL is 100 units, so multiply mL by 100. 0.3 mL is the same as 0.3 cc.

How much of the vial 0.3 mL is

A draw of 0.3 mL (30 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.

Questions

How many units is 0.3 mL?

30 units on a U-100 insulin syringe. 1 mL is 100 units, so multiply mL by 100.

Is 0.3 mL the same as 0.3 cc?

Yes. A cc and a mL are the same volume, so 0.3 cc is also 30 units on a U-100 syringe.

How many units is 0.3 mL on a U-40 syringe?

12 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 0.3 mL?

Multiply 0.3 mL by the concentration in mg/mL. At 5 mg/mL it is 1.5 mg; at 10 mg/mL it is 3 mg.

How much of a vial is 0.3 mL?

Divide 0.3 by the mL of water added. If 2 mL was added, 0.3 mL is 15% of the vial.
