In America, the pair of continents are know as "the Americas". Every American knows singular 'America' refers to America.

> But in other countries we say-

Other countries exist?

More importantly, in English, America is the US and the Americas are the continents.

It is sort of irrelevant what other countries call America or if they divide up the continents differently. Other languages name things differently.
