I am becoming quite used to...

... everything measured in grams or kilograms
... the second set of directions being given in Arabic instead of Spanish
... "military time" or 24-hour time rather than 12-hour A.M. and P.M.
... seeing everything in Celsius rather than Farenheit
... driving/walking on the left side of the road
... roundabouts instead of intersections
... referring to distance and speed in kilometers
... recognizing and writing the date in the European order of day/month/year. Thus, 7/3/2011 is actually March 7, 2011and not July 3, 2011
