I'm writing a scientific paper about two obtained results: an experimental result and a numerical one. Because the two agree well with each other, I may use the term "agreeability" to describe their relation. For instance, I may write "a good agreeability of the numerical result with the experimental one was achieved". However, after searching on the web I found that the term "agreeability" is uncommon (actually, this website regards it as an orthographic error) and it is better used when describing someone's personality trait.
I ask you then some other words that may replace the term "agreeability" and could be used within a scientific context. I know that I could write something like "thing A agrees well with thing B", which is correct, but I really would like a single word (or not much more than one), more specifically, a noun that could describe the relation.
