Google has an interesting localization issue when it comes to Canada. If you ask it for someone's height, it gives it in metric, but everyone here uses imperial for body related measurements. The same goes for area, I hear acre a lot more than hectare, but "How big is disneyland" gives me 65ha.
There must be a name for this syndrome - tendency of US-based developers to over-exoticize foreign places, taking at face value all official units of measure, languages, etc.
