This is a bit of a strange question…
I’m building a location-aware iPhone app that displays distances from the device to various points of interest. We use metric measurements down here in Australia, but the user will have the option to display data in imperial units if they choose.
My question – should I use miles and yards, or miles and feet as my units for USA-based users? What is more typical? And if anyone from other imperial-using countries want to weigh in, feel free (do you Brits still talk imperial units?)…
Google Maps is as good a place as any to reference for this decision.
They seem to use fractional miles (to one decimal place) down until 0.1 miles, then switch over to feet.
