10 units to mL
For a U-100 insulin syringe, 10 units to mL, plus which syringe it fits and the peptide amount at common strengths
On a U-100 insulin syringe, 10 units is 0.1 mL.
With a U-40 syringe, 10 units comes to 0.25 mL. The amount fits a U-100 syringe marked 0.3 mL (30 unit).
10 units marked on an insulin syringe
Since 1 mL holds 100 units in a U-100 syringe, one unit measures 0.01 mL. They show volume only. The strength of your mix decides how much peptide fits in that volume.
| Strength of your mix | Amount in that volume | In mcg |
|---|---|---|
| 1 mg/mL | 0.1 mg | 100 mcg |
| 2 mg/mL | 0.2 mg | 200 mcg |
| 2.5 mg/mL | 0.25 mg | 250 mcg |
| 5 mg/mL | 0.5 mg | 500 mcg |
| 10 mg/mL | 1 mg | 1,000 mcg |
Which line do you draw to?
Each line marks 1 unit on syringes of 0.3 or 0.5 mL, so count 10 lines. Each line marks 2 units on a 1 mL syringe, so 10 units takes 5 lines.
