20 units to mL
The 20 units to mL value for a U-100 insulin syringe, the syringe that fits, and the peptide amount at common strengths.
With a U-100 insulin syringe, 20 units is 0.2 mL.
The same 20 units would measure 0.5 mL on a U-40 syringe. The amount fits a U-100 syringe with a 0.3 mL capacity and 30 unit marking.
What peptide amount does 20 units hold?
Each unit on a U-100 syringe is 0.01 mL, because 100 units fill 1 mL. They show volume and nothing more. The peptide amount in that volume depends on the strength of your mix.
| Strength of your mix | Amount in that volume | In mcg |
|---|---|---|
| 1 mg/mL | 0.2 mg | 200 mcg |
| 2 mg/mL | 0.4 mg | 400 mcg |
| 2.5 mg/mL | 0.5 mg | 500 mcg |
| 5 mg/mL | 1 mg | 1,000 mcg |
| 10 mg/mL | 2 mg | 2,000 mcg |
Which line do you draw to?
When the syringe is 0.3 or 0.5 mL, every line marks 1 unit, so count 20 lines. Each line on a 1 mL syringe is 2 units, which means 20 units is 10 lines.
