4.4.1.717.1 Definition

Unified Code for Units of Measure (UCUM). This value set includes all possible UCUM codes used for distance measures - that it is, all units which have the same canonical unit as 'm' (metre)

4.4.1.717.2 Content Logical Definition

Generated Narrative: ValueSet all-distance-units

Last updated: 2026-03-18T02:54:13.541Z

Include codes fromhttp://unitsofmeasure.org version Not Stated (use latest from terminology server) where canonical = m (m)

Explanation of the columns that may appear on this page:

Lvl

A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information

Source

The source of the definition of the code (when the value set draws in codes defined elsewhere)

Code

The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')

Display

The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application

Definition

An explanation of the meaning of the concept

Comments

Additional notes about how to use the code
