I created test sensors for different dev_classes - here is a code-generator below.
Probably my test is wrong since I am using input_number values which do not have device_class specified, but they have UoMs specified.

So, I do not see any changes in presentation if UoM is specified - only difference is that UoM is displayed after the value.
Exceptions:
- “duration” is displayed w/o UoM in “hh:mm:ss” format (which does not occur if UoM is not specified);
- “monetary” - no UoM is displayed for sensor:
Also, I changed UoM for some values to see what could happen.
For example, for “frequency” - the value was “xxx MHz”, I changed UoM to “Hz” and reloaded templates - the displayed value is “xxx Hz”:
As for temperature: initially the sensor has UoM =C, then I changed to F - and the value is changed (not correct), UoM not changed:
