Long I've never heard that before, but in a quiz show I watched last week, the contestant was asked "Viking Leif Erikson established the first permanent settlement on which island?". Her two guesses were Iceland and Alaska, and she eventually went for Iceland. Why the host never told her that Alaska wasn't an island, I don't know. The answer is actually Greenland!

I'm old enough to have learned both of the common scales, but have been using Celsius (or Centigrade as we were originally taught it) for many years now. Some useful conversions are: 0°C is 32°F, 30°C is 86°F and 100°C is 212°F. If you go somewhere really cold it gets very easy because -40°C is -40°F. I'm sure you've got an app to do the conversion, but otherwise you'll need to subtract 32 and divide by 1.8 (subtracting 30 and dividing by 2 gives a good approximation at normal temperatures and is easier to calculate in your head). I found a 2016 article which suggests that Fahrenheit is now only used by the United States (and associated territories), the Bahamas, Belize, the Cayman Islands and Palau. Don't forget that your car will measure speed and distance in miles because the United States (and Myanmar and Liberia) are still using Imperial measurements. Of course your gas will still be measured in gallons, but US gallons are only about 3.8 liters instead of the 4.5 liters that used to be in everyone else's Imperial gallon (so the fuel consumption isn't as bad as you thought!). At least you'll only be paying about €0.60/liter, which is about 40% of the price in the Netherlands (even Ireland is cheaper!)
