| 11 | For any substance that is not U-100 insulin, the unit markings are therefore simply a volume scale in which one mark equals 0.01 mL. This is the whole of the conversion, and it is the source of most of the confusion surrounding these devices when they are used for other preparations. See [[Insulin syringe unit conversion]].{{r|usp797}} | 11 | For any substance that is not U-100 insulin, the unit markings are therefore simply a volume scale in which one mark equals 0.01 mL.

| + | 13 | Their prevalence in this context follows from the volumes involved. A dose of a few hundred micrograms of a peptide at a few milligrams per millilitre is a volume of tens of microlitres, which a 1 mL syringe measures poorly and a 0.3 mL syringe measures adequately.{{r|iso7886}} | |

| 14 | A 0.3 mL syringe is graduated in single units, sometimes in half units; a 1.0 mL syringe usually in two-unit increments. Finer graduations on a smaller barrel give better resolution for small volumes, which is why barrel size is chosen to suit the volume rather than for convenience.{{r|iso7886}} | 16 | A 0.3 mL syringe is graduated in single units, sometimes in half units; a 1.0 mL syringe usually in two-unit increments.
