An error encountered on the fs table by @DLafayetteII raises an interesting question:
How do we wish to handle units that are not in the unit registry?
Currently we error out at time of creation of the channel/variable
We could:
- status quo
- Drop units for non-standard units (with warning, but not error)
- accept non-standard units, but disallow conversions when they are not in the registry
The particular case that was encountered is a tad bit more tricky than standard "not in registry", which can ordinarily be checked with unit in wt.units.ureg.
This particular unit was "%", which pint treats as an operator, thus it raises a SyntaxError subclass when checked if it is in the registry.
See also wright-group/bluesky-in-a-box#47 for a workaround in that application.
