This question already has an answer here:
I understand that for a countable noun, one is supposed to use the singular form if and only if the number is equal to one or negative one; for example:
- one degree
- negative one degree
- 0.75 degrees
Now my question is, what if the number is not expressed explicitly as one or negative one, but is essentially equal to one? For example, which of the following is correct:
- 1.0 degree or 1.0 degrees?
- negative four over four degree or negative four over four degrees?
Edit: I just realised that for the difference between 1.0 degrees and 1.0 degree, it has been answered here. However, the question about negative four over four degree or negative four over four degrees remains unclear to me.
