What is 10 units on a syringe in mL?
10 units is a volume. On a U-100 syringe it is 0.10 mL, on U-50 it is 0.20 mL, and on U-40 it is 0.25 mL. How many mg that holds depends on concentration: mg = mL × mg/mL. At 2.5 mg/mL (5 mg in 2 mL), 10 U-100 units = 0.10 mL = 0.25 mg (250 mcg).
The math
mL = 10 ÷ 100 = 0.1 (U-100) mL = 10 ÷ 50 = 0.2 (U-50) mL = 10 ÷ 40 = 0.25 (U-40) mg = 0.1 mL × 2.5 mg/mL = 0.25 mg
| Concentration | mg in 10 U-100 units | mcg |
|---|---|---|
| 1 mg/mL | 0.1 | 100 |
| 2 mg/mL | 0.2 | 200 |
| 2.5 mg/mL | 0.25 | 250 |
| 5 mg/mL | 0.5 | 500 |
| 10 mg/mL | 1 | 1000 |

10 units
= 0.1 mL · concentration 2.5 mg/mL (2500 mcg/mL) · 20 draws per vial
Concentration = 5 mg ÷ 2 mL = 2.5 mg/mL Volume = 250 mcg ÷ 2500 mcg/mL = 0.1 mL Units = 0.1 mL × 100 (U-100) = 10 units
