30 units to mL
With a U-100 insulin syringe, this 30 units to mL guide explains the matching syringe and peptide amounts at common strengths.
On a U-100 insulin syringe, 30 units measures 0.3 mL.
A U-40 syringe would need 0.75 mL for those same 30 units. This amount works with a U-100 syringe marked 0.3 mL (30 unit).
What amount of peptide does 30 units hold?
Each U-100 syringe holds 100 units per 1 mL, so one unit is 0.01 mL. Units show volume only. 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 | 0.3 mg | 300 mcg |
| 2 mg/mL | 0.6 mg | 600 mcg |
| 2.5 mg/mL | 0.75 mg | 750 mcg |
| 5 mg/mL | 1.5 mg | 1,500 mcg |
| 10 mg/mL | 3 mg | 3,000 mcg |
Which line do you draw to?
For 0.3 or 0.5 mL syringes, every line equals 1 unit, so count 30 lines. Each line on a 1 mL syringe is 2 units, so 30 units takes 15 lines.
