Clarification on monitor match?

[ScottyFPS]

I’m trying to understand the math behind monitor match, specifically 0%. From what I gathered so far, 0% is the tan ratio between two fovs, but what I don’t understand is how exactly does this work when converting to and from the desktop?

Any help is appreciated.

Do you just want to know the math or the principles behind it?

Both, actually. The more knowledge the merrier.
