This question already has an answer here:
This question is different from Why do English writers avoid explicit numerals?, as it is about the usage in a physics research paper.
Basically, I am not sure when to use Arabic numerals and when to use their corresponding English words when writhing a physics research paper.
- The 3 parameters are fixed.
- The three parameters are fixed.
- The value of the parameter is five.
- The value of the parameter is 5.
Are 1 and 2 both acceptable? Or is one of them better perceived? And again, is 4 better than 3?
If 4 is better than 3, and 2 is better than 1. I can then have both numerals and words to represent small numbers in a paper. Is this acceptable?
Can I always use Arabic numerals?
