Summary

Defining URL: http://hl7.org/fhir/StructureDefinition/extension-quantity-translation

Version: 5.0.0-ballot

Name: QuantityTranslation

Title: Quantity Translation

Modifier: This extension is not a modifier extension

Status: draft

Definition: An alternative representation of the same physical quantity expressed in a different unit from a different unit code system and possibly with a different value.

Committee: FHIR Infrastructure Work Group

Status: draft. Extension maintained by: Health Level Seven International (FHIR Infrastructure)

An alternative representation of the same physical quantity expressed in a different unit from a different unit code system and possibly with a different value.

Comment:

It is not necessary for information processing entities to check and enforce that the translations are valid translations of the base unit, but they are allowed to do so, and to reject instances where the translations are not valid. NOTE Translations are allowed to contain other representations in UCUM units, but there is generally no point to this as it is possible to convert from one UCUM form to another.

Context of Use: Use on Element ID Quantity
