Handling alternative English names against the SI Digital Framework #111
Description
For the quantities, we have the SI names as well but as the secondary name. Perhaps we can promote them to the primary name (except for the degree Celsius symbol which we will not do).
For the units, we have US English of meter and liter. We need to be able to distinguish them using perhaps BCP 47 codes of en-US vs en (if we take metre and litre as official names, I mean, yes they are...).
There are additional SI units that we don't have, which are legacy realizations of the base units. I wonder if we to incorporate them in UnitsDB (probably).
