let locale = Locale.current //NSLocale.current

//Returns true if the locale uses the metric system (Note: Only three countries do not use the metric system: the US, Liberia and Myanmar.)
let isMetric = locale.usesMetricSystem

//Returns the currency code of the locale. For example, for “zh-Hant-HK”, returns “HKD”.
