Units Used In Medicine

This dataset lists example unit terms that are commonly used in medicine. Since the space of possible unit terms is infinite in theory and very large in practice, no attempt has been made on a systematic coverage of possible units. All necessary units can be built from the rules of The Unified Code for Units of Measure and there is no need for a particular term to be enumerated in order to be valid.

Description
When a special conversion function is specified, the conversion takes more than multiplication with a factor. Implementers should consult the Unified Code for Units of Measure (UCUM) specification or the reference implementation for details on how to apply these conversion functions.
The example unit terms are given with alternatives for the following reason. The source of the example terms is the HL7 version 2.4 specification of chapter 7. To show the essential differences between Unified Code for Units of Measure (UCUM) and the HL7 version 2.4 codes, the first column shows unit terms that are as similar to the HL7 2.4 published terms as possible. However, the HL7 version 2.4 suggested unit terms were sometimes unnecessarily complicated (e.g., the unit 1 dyn cast as 10 μN; decimal factors instead of the standard multiplier prefixes, nested parenthetical terms in divisions, etc.), even sometimes suggesting deprecated conventional habits (e.g., using annotations like “/g{HGB}” instead of just “/g”.) Hence, the second column “alternative suggestions” lists equivalent unit terms that are either more straightforward or more appropriate or both.
