Since you take a British English dictionary for the definition of The Americas
You're sure that it's a "British English" dictionary? All its sources include both British and American texts. OED is supposed to be "the definitive record of the English Language", leaving nothing important out. (Not even Aussies!) Sure, if you were talking about one of the "concise" versions, that would make sense - there's the Oxford Dictionary of English which is based on the British National Corpus, and its American English counterpart, the New Oxford American Dictionary, which is based on an American English Corpus. But a suggestion that the OED itself (which is a distinct work from both) is a "British English dictionary" sounds preposterous to me.
So whenever I need to refer to the Commonwealth of Nations, I'll just call it "Britain". The dictionary says so.
Webster as an authority? Sure, if you're bold. The thing is, I've never seen anybody to refer to the Commonwealth of Nations as just "Britain", but everyone around here in Europe uses "America" either for the US, or for the combined NA+SA landmass, quite unambiguously based on the context.
