Vial to Units

1 mL to units

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

How much of the vial 1 mL is

A draw of 1 mL (100 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 1 mL?

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

Is 1 mL the same as 1 cc?

Yes. A cc and a mL are the same volume, so 1 cc is also 100 units on a U-100 syringe.

How many units is 1 mL on a U-40 syringe?

40 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 1 mL?

Multiply 1 mL by the concentration in mg/mL. At 5 mg/mL it is 5 mg; at 10 mg/mL it is 10 mg.

How much of a vial is 1 mL?

Divide 1 by the mL of water added. If 2 mL was added, 1 mL is 50% of the vial.
