   US and UK miles are identical. 'Nautical miles' however, are different from   
   land miles: "exactly 1,852 meters (about 6,076 feet)" compared to 5280 feet   
   for land miles - in both the US and UK.   
      
   In Canada, metric measurements are supposed to be used, though US measurements   
   are typically used on building supplies because the market for these is North   
   America-wide. The result is that packaged grocers often have odd   
   package-sizes, with what would be a US-standard size is converted to an odd   
   sounding number of millilitres or grams.   
      
   Even when working just in metric, confusion can occur. In Canada, for   
   instance, beer bottles and servings are measured in millilitres - 375 ml, for   
   instance - which confused me (and the server) the first time I was asked what   
   size beer I wanted in France, where the serving size is in centilitres. 375 CL   
   is a very large glass!
