| 9 | This is the single most consequential fact on this page, and the source of the errors it exists to prevent. A "10 unit dose" is a statement about volume; it means 0.1 mL, and it says nothing about milligrams until a concentration is supplied. Where a solution has been reconstituted by the user rather than filled by a manufacturer, no syringe marking can carry information about its strength. | 9 | This is the single most consequential fact on this page, and the source of the errors it exists to prevent.

| + | 11 | Two other scales remain in circulation. U-50 syringes use a 0.5 mL barrel with the same 0.01 mL graduation, giving finer visual resolution for small volumes. U-40 syringes, still used for veterinary insulin in some jurisdictions, place 40 units in 1 mL, so one unit is 0.025 mL — two and a half times the U-100 unit.{{r|iso8537,fdavet}} | |
