Peptide Calculator
Enter the amount on the vial, the liquid added, and the amount already chosen for one administration. The calculator converts that amount into liquid volume and U-100 syringe units.
— units on a U-100 insulin syringe
Concentration: 2.5 mg/mL
Use explicit units and recheck every value. Vials are commonly labeled in mg, while small per-administration amounts are often discussed in mcg. On a U-100 syringe, 100 units = 1 mL.
The vial amount divided by liquid volume gives concentration. The chosen amount is converted to mg, divided by concentration for mL, then multiplied by 100 for U-100 syringe units.
The calculation checks units and syringe capacity. It does not determine whether the desired amount is appropriate.
