Apparently the Bahamas, Belize, the Cayman Islands, the Republic of Palau and the United States are all countries that use the Fahrenheit scale whereas all other countries in the world use Celsius to measure temperature.
Do you know your Celsius?
Should Celsius be the temperature scale by default when talking temperatures, after all it's the most used scale?
I first memorized "Fahrenheit equals nine fifths Centigrade plus 32" in elementary school. I still routinely convert Celsius to Fahrenheit when I want to compare the two rather than the other way around.
I could change, but I'd still have to re-associate the feeling of a given temperature with a number.
Either way is fine with me.
