These are the numbers for the "custom scale" box in a print dialog. "Fit to page" computes the same thing, but knowing the figure tells you in advance whether the result will look deliberate or accidental.
Why the shapes matter
The proportions differ: B1 is 1:1.41 and ARCH E1 is 1:1.4. That difference is why a layout moved between them never quite lines up — scale it to fit one edge and the other is left with 7.8 mm of unwanted margin.
