Does this Mac use the metric system? 1

I’m writing a small application that interacts with iWork templates. Now iWork has two sets of templates; a “Traditional” set using the Imperial measurement system (inches, US Letter page size, etc), and an ISO set for the Metric measurement system (centimetres, A4 page size, etc).

The issue I faced was which templates to interact with. An American user would want to learn about the Traditional set, but an Australian or European user would want to find out about the ISO set.

Unfortunately, the Cocoa API doesn’t include a method for determining what measurement system is in use. But a quick search on CocoaDev reveals that Carbon does:

Boolean IsMetric ();

Cocoa developers just need to import the Carbon framework into the relevant .h file and IsMetric() away!
