Feature Request - Create blood glucose (mmo/l - mg/dL) & hba1c (mmol-mol) - (percent)

[kgrosvenor]

Just a another set of units you could add 👍

[jiminikiz]

If you would like to add these units, feel free to submit a pull request following the design patterns of the library. Pull Request #51 might also allow the library to add units on the fly for custom units not currently built into the library.

If not, I will see when these units can be added. Digging through current issues and pull requests to see what is the easiest to add / fix first.

@jiminikiz I've already did this conversion, if you can advice me to which unit group should this conversion goes I can create a PR right away

We may need a new definition, concentration to handle all mass per unit volume scenarios. Perhaps density measures should also go into the same file.

Seems like different variants of concentration are possible:

1. Mass/Mass

• wt%
• wt ppm
• kg/kg Ⓜ️
• g/kg Ⓜ️
• mg/kg Ⓜ️

2. Mass/volume

• lbm/bbl
• g/US gal
• g/UK gal
• lbm/1000 US gal
• lbm/1000 UK gal
• gr/US gal
• gr/ft^3
• lbm/1000 bbl
• mg/US gal
• gr/100 ft^3
• kg/m^3 Ⓜ️
• g/m^3 Ⓜ️
• mg/m^3 Ⓜ️
• g/dm^3 Ⓜ️
• g/L Ⓜ️
• mg/dm^3 Ⓜ️

mg/dL could go into above.

3. Volume/volume

• ft^3/ft^3
• bbl/acreft
• vol%
• UK gal/ft^3
• US gal/ft^3
• mL/US gal
• ml/UK gal
• vol ppm
• UK gal/1000 bbl
• US gal/1000 bbl
• UK pt/1000 bbl
• m^3/m^3 Ⓜ️
• dm^3/m^3 Ⓜ️
• cm^3/m^3 Ⓜ️
• L/m^3 Ⓜ️

4. Mole/Volume

• (lbmol)/US gal
• (lbmol)/UK gal
• (lbmol)/ft^3
• std ft^3/bbl
• kmol/m^3 Ⓜ️

mmol/l could go into above.

5. Volume/mole

• US gal/1000 std ft^3
• bbl/million std ft^3
• dm^3/kmol Ⓜ️
• L/kmol Ⓜ️

6. Mol/Mol

mmol/mol could go into above.

The range of units is large and there can be valid reasons to not support all of them. But should we start by just supporting metric/SI units as concentration is quite a useful unit of measure? @Taar Does it look like a good v3 candidate? I can help with the PR if needed.

Any update on this one? How can I support density units (mass/volume)? Is it possible with custom unit definitions?

@cchamikara can you please share the code block how you did it?

[poof86]

I also need this, please share :)
