Poll Results

Without cheating, how long was my recent 3.2km run?  All four of you selected 2 miles, which was correct.  It's about 1.99 miles. 
I haven't gotten a lot of the conversions down yet.  Here are some key differences:

• My weight should be in kilos, not pounds
• My height in meters, not feet or inches
• Meat at the deli counter is in grams, not pounds
• Electricity is 220v (or 240v?), not 110v
• The marathon is in kilometers, not miles
• The freezing temperatures back home must be described in celsius, not fahrenheit
• Seasons are hot, more hot and really hot, not spring, summer, fall and winter
• Lights on flip down, not up
• My deadbolt turns counterclockwise to lock, not clockwise
• Allen wrenches/screws are in metric, not English
• Clothes sizes can be almost anything - don't get stuck on a number
• My shoes are 39/40, not 8.5/9
• Walking and driving are on the left, not the right
• Work days are closer to 9 to 7 than 8 to 5
• Football is soccer, not football
• Christmas is Christmas, not a politically correct "holiday"

These are most of the main ones that come to mind.
