Should `A` stand for angstrom or ampere? about pg HOT 3 CLOSED

If it doesn't break a bunch of things and isn't too hard to do, I'd be in favor of the change. The SI symbol for the ampere is A (it's one of the seven SI base units), and I agree that it is much more likely for end users to mean ampere than angstrom if they put in that symbol.

That said, it's also not that hard to work around if changing the symbol would break things.

I also think A should stand for ampere.

The only references to Angstroms in the OPL are help files:

• OpenProblemLibrary/macros/FortLewis/AnswerFormatHelp.pl
• OpenProblemLibrary/Michigan/units.html

The question is whether you want a gradual transition or you like the Big Bang approach.

Either way, the first step is to add the new unit for Angstrom to Units.pm so that the help files in WW and OPL can be updated when the new unit is available in production.

I've just opened PR #753 to add some new units. The new angstrom could be added to that PR for convenience or separated out in its own PR for faster merging to main.

We've merged in some changes (listed above) to handle angstroms.
