Answer 1

You can get the locale that the phone is set to this way:

NSLocale *locale = [NSLocale currentLocale];

and ask it about units of measure this way:

NSString *measurementSystem = [locale objectForKey: NSLocaleMeasurementSystem];

This will answer “Metric” or “U.S.”. There’s a lot more you can check in the NSLocale class ref.
