I once made me own 0 to 5 scale.

0/5 – Literally hate each other
1/5 – Well, at least they don't hate each other
2/5 – They are on at least friendly terms
3/5 – They're friends
4/5 – They're rather close friends
5/5 – Actually in a relationship
6/5 – The characters don't really exist outside the relationship
