Answer
Otherwise, AI uses your available country context across Text answers and Image, Video and Audio prompt preparation, including hashtags and scheduled generation. For Canada, weather defaults to Celsius first and general measurements to metric. Asking about another country does not automatically change your preferred units.
The same defaults apply in private and People chats on web, phone browsers, iOS and Android, without a new setting. Location context can be missing or stale, so tell AI your preference or correct your country when necessary. Without a country or requested preference, measurements use labelled metric units and Celsius.
Exact quotations, translations, supplied data, code and required file formats preserve their values and syntax. Currency and jurisdiction-specific standards are not silently changed. AI can still make formatting or conversion mistakes.
