A scale linked to its intended purpose
An insulin syringe may carry a unit scale associated with the insulin concentration it was designed for. Those markings do not express milligrams of any substance. Units, volume and mass are different concepts.

Recognizing an incomplete description
If a document says only units, the unit definition and context are missing. The FDA has documented errors involving confusion between units, mL and mg. For a technical review, preserve the original units and flag ambiguity without inferring equivalence.

Does units always mean mL?
