Add missing UCUM units

[keilw]

At the moment at least

SECTIONS §41-§43 skipped; implement later if needed

are missing from the UCUM system.

@keilw , I want to introduce you to a GlobalMentor developer @magnonasc. I'm going over the UCUM tasks right now. If you want you can assign this issue to him.

@garretwilson @magnonasc Thanks y lot for helping out with this.

Although there are a lot of UCUM units that are missing, there are a lot of types that still doesn't exist in the api, such as the units for fluid resistance, or refraction of a lens , or slope, so I'll add what I can, but I'll leave the ones that we don't have a type for when they're created in the api... It might be an issue for unit-api aswell. Nevermind, you have dimensionless that might be enough.

Please feel free to add quantities you are feel better suited than Dimensionless to https://github.com/unitsofmeasurement/uom-systems/tree/master/quantity

[magnonasc]

Sure, thank you!

I use the UCUM system in the context of FHIR which is a standard for health care data exchange. FHIR defines a ValueSet of UCUM units which are used in the medical domain. Not all of this units are parseable by this implementation. Today I had especially the request for 10*3/uL (samply/blaze#232) with is defined as "Thousands Per MicroLiter". Is the form 10*3 really defined in UCUM? I'm not sure.

What can I do to get more of the units in FHIR interest into this implementation?

Back in August I was experimenting with the UCUM implementation and found that the UCUM [drp] "drop" (a volume) was also not supported. However, this was not one of a group of units just commented out in the implementation, I think it was missing completely. There is a set of functional tests for UCUM that we could look to validate against? https://ucum.org/trac/wiki/FunctionalTests

Thanks for the input, we also had #173 but there was no feedback about retesting it after many units have been added to the latest SNAPSHOT already. Maybe you could give it a try instead. For very healthcare specific units that are not covered by UCUM we could use the Domain Health module and define what's necessary there.

Hi, be willing to contribute if someone can give a rundown of what needs to be added? thx

[alexanderkiel]

I like to have [arb'U]. This is properly related to #174.
