Celsius
Or Centigrade, as it used to be called.

fuck Mr Celsius
any cunt could have come up with that temperature scale and so I see no reason why his name should be on it

Holy shit, they're the same?
I always used to just say 'C' because I wasn't sure. Little did I know I could have said what the hell I liked.

Yup
Centigrade, because there are a hundred degrees between the two fixed points, and Celsius because Anders Celsius was the first to get off his arse and do something about standardising the scale.

Edit - although of course he had it arse for tit first time round with 0°C for boiling water and 100°C for freezing point.

I'm always going to use this one.
Because I hate it when people text me from Turkey saying "It's 21 degreeeees!" and I think "So fucking what, when I went to Spain it was in the 90s. You'd better get a refund."
