What about the North and South Poles?
I'm sure standard coordinate systems have a convention for representing them.
Won't we need lots of units that are not SI units (e.g. base pairs, IQ points, Scoville heat units, $ and €) and can't readily be translated into them? Why would historical units with unknown conversions pose any more problem than these?
These all pose the same problems, correct. At the moment, I'm very unsure about how to accommodate these at all. Maybe we can have them as "custom units", which are fixed for a given property, and can not be converted.
