:I don't know if I really count as a third opinion, but I don't have particularly strong feelings about American of Commonwealth English (AE/CE). I consistently (try to) write and speak the former, but that's about it. As far as I'm concerned, there's really no "European English" that should automatically apply to anything other than the UK and Ireland. I'm sure an older generation of second language speakers and writers believe that, but I don't see that it's the case among a younger generation. If the article subject is about something clearly and narrowly associated with the Commonwealth countries, CE should be used. If it's an international topic, I would recommend using whatever variant was clearly employed first. 
 :Btw, the article right now has both "centimetres" and "centimeters". That's definitely not a good idea, so I would at least recommend reverting to a certain variant consistently or not at all.
