Re: [Wikidata] Units

Sorry for long rant! 1. How do I get/set the list of base units (try "foot" and then ask yourself "which foot is this?" [4]) 2. How do I get/set derived units (Siemens is the inverse of Ohm, that is S=Ω⁻¹ [3]) 3. How do I add prefixed units (1kΩ, and 1mΩ, and note there is a bunch of non-standard prefixes - not to forget localized ones! [5] I hate the mess on Wikipedia... And note the mess with kilogram[7]) 4. How to normalize a unit (it is (nearly) always µF, even when you write 4700µF [6] - this text is so messy and it does not really address the problem) 5. Is there any plan to handle deprecated units (the weight prototype gaining weight[1], and the new proposed standard [2] is one known problem 6. How to disambiguate units (the feet-problem in another version) 7. Is there any plan to add warnings about units that needs disambiguation (the feet-problem is well-known, but how about kilogram? And note that is the kilogram that is the standard unit, not the gram.) 8. How to handle incompatibilities between unit systems (you can't convert some old units to newer ones.)
