How this calculator works

Concentration

The vial strength divided by the water you added. A 10 mg vial in 2 mL gives 5 mg/mL.

Volume

Your selected amount divided by that concentration, which gives the volume in millilitres.

Syringe units

On a U-100 insulin syringe, 100 units is 1 mL, so the volume is multiplied by 100.
