#### Unit of measurement of entities
Integrations can provide translations for units of measurement of its entities. To do this, provide an `entity` object, that contains translations for the units and set the entity's `translation_key` property to a key under a domain in the `entity` object.
-If the entity's `translation_key` property is not `None` and the `entity` object provides a translated unit, `SensorEntityDescription.native_unit_of_measurement` and `NumberEntityDescription.native_unit_of_measurement` will be ignored.
