Step 1 of 4

  1. How many mg are in your vial?
    Vial strengthamount printed on the vial
  2. How many mL of water did you add?
  3. What dose do you want to convert?
  4. Which syringe are you using?
Draw to
50.0units

0.50 mL · 5.00 mg/mL · 50 mcg per unit · 4 doses per vial

50.0 units on a U-100 insulin syringe · 1 mL · lines every 2 units, which is 0.50 milliliters. The draw lands on a syringe line.

Easy to read on this syringe. Draw to the 50-unit line. No rounding is needed.

10 mg ÷ 2 mL = 5.00 mg/mL
→ 50 mcg/unit · 2.5 mg = 0.500 mL = 50.0 units

Can this syringe show the result clearly?

Easy to read on this syringe. 50.0 u is exactly the 50-unit line on a U-100 — no rounding error at all.

Want an easier syringe number?

This setup is already easy to read. Changing the water between 0.5 and 3 mL would not put 2.5 mg closer to a line on this U-100 syringe.

Adding more water makes the mixture less concentrated, so the same dose uses more syringe units. It does not change how much peptide is in the vial.

This setup is in the address bar — every input is part of the link.
