keeveek: Yep, Fahrenheit degrees are also not very usable, compared to Celsius.
Celsius is simple. You see minus in front of the temperature? It's freaking cold, dude.
And the water boils in 100 degrees celsius and 212 degrees Fahrenheit. Funny :P
For science Celsius definitely makes more sense, but for everyday living Fahrenheit is a much more useful scale. Mostly because you're nearly always in positive territory whereas with Celsius you routinely end up being in negative territory without it being particularly cold.
Different scales for different purposes. Fahrenheit goes from the coldest water gets to roughly body temperature, for most things it's a perfectly reasonable scale to use.
bazilisek: Nope. 100 was supposed to be body temperature, but because that's a value that fluctuates a lot and because Fahrenheit's measurements were imprecise, it simply isn't true. As for the 0, no one knows what that was supposed to correspond to. It's defined as a freezing point of some kind of water-based mixture today, but that's just a back-definition.
keeveek: So it's fucked up, and they still use it, funny again ;p
What's funny is that you seem to think that metric is better than imperial. The fact is that unless you're a scientist there's very little reason to use metric over imperial measures. What's more imperial does have a few advantages such as being more suited to fractions and not requiring one to go into negative territory just because it's slightly below freezing.
Overall, anybody mocking people for using the other system had better not be serious.
