@Smalyshev @Esc3300: When extracting conversion factors from statements on Wikidata, we should only use factory that are marked +/- 0. +/-0 indicates that the factory applies per definition, which is what we want for conversion.
For things like calendar year, month, or historical units, the conversion factor should be given with some uncertainty.
Thinking about it, we could even uncertain conversion factory, but we would need to carry the uncertainty through the conversion mechanism, applying it during conversion. Possible, but I don't think we need that right now, and it would complicate things quite a bit.
