Is it grammatically correct to say it's 1 degrees outside or is it 1 degree outside? (Talking about the weather in Buffalo, New York.)
I would say 1 degrees is correct. We are not discussing an amount of things. 1 is not number of degrees that exsist. It isn't the same as saying 1 cookie. Rather 1 is an idication of your possition on a scale called degrees. I would even venture that it is incorrect to say 1 degree celcius or fahrenheit.
