Finding the distance, currency, temperature units etc. for a country (iPhone)

During the localization of my app I went through a lot of documentation, somewhere Im sure I read that there is a way to get a set of units that is linked with the locale.

I believe it said something like "units based on cultural..." something.

I would like to display temperature and distance in Fahrenheit and Miles for some countries and Celsius and Kilometers for other countries.

Is there a way to access a list of these units in the iPhone SDK.

Thanks you.

You can use NSLocale to check the currency unit, but for imperial vs. metric you need to make a list yourself.

Oops. You can check for the imperial vs. metric. There is are NSLocaleMeasurementSystem and NSLocaleUsesMetricSystem keys.

I have extracted this method to String extension. Looks elegant

Swift 4.1 version

import MapKit

extension String {
    init(distance: Double ) {
        let mkDistanceFormatter = MKDistanceFormatter()
        mkDistanceFormatter.unitStyle = .abbreviated
        self = mkDistanceFormatter.string(fromDistance: distance)
    }
}

Usage 

let distance = Double(34234.0)
let stringDistance String(distance:distance)
