50 units to mL
50 units to mL for a U-100 insulin syringe, including the syringe it fits and the peptide amount at common strengths.
On a U-100 insulin syringe, 50 units equals 0.5 mL.
The same 50 units would equal 1.25 mL in a U-40 syringe. The syringe that fits is 0.5 mL (50 unit), marked U-100.
How much peptide does 50 units contain?
With 100 units in 1 mL, a U-100 syringe gives you 0.01 mL per unit. Units show you the 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 | 0.5 mg | 500 mcg |
| 2 mg/mL | 1 mg | 1,000 mcg |
| 2.5 mg/mL | 1.25 mg | 1,250 mcg |
| 5 mg/mL | 2.5 mg | 2,500 mcg |
| 10 mg/mL | 5 mg | 5,000 mcg |
Which line should you draw to?
Each line marks 1 unit on syringes of 0.3 or 0.5 mL, so count 50 lines. Each line on a 1 mL syringe is 2 units, so 50 units comes to 25 lines.
