  "description": "UCUM (the Unified Code for Units of Measure) -- the code system FHIR uses for units on `Quantity`,\nand the system this specification's quantities carry: observation values, medication strengths and\ndurations.\n\nUCUM is unusual among the systems here in that it is a **grammar rather than a list**. Codes are\ncomposed from base units and prefixes according to a specification (`mg`, `mg/dL`, `mm[Hg]`,\n`10*6/uL`), so the set of valid codes is infinite and no enumeration of it exists or could. A\nconsumer validates a UCUM code by parsing it, not by looking it up.\n\nPublished by the **Regenstrief Institute** and the UCUM Organization. The specification, the tables\nand the terms of use are at <https://ucum.org>.\n\nThe canonical URI is `http://unitsofmeasure.org`.\n\n**The set enumerates no codes of its own.** It includes the whole system, so it means every code in it, and it exists so the system URI resolves to a definition rather than to nothing. The definition itself stays with the publisher at the canonical above: this specification does not redefine the system and does not restrict it. Where this page shows a list of codes, that list is a SAMPLE reproduced under the publisher's own terms and is not the set's content -- the page says how many of how many it is showing.",
