the scale factor is predictable, you would need to make your original
drawing 80% of its current size. Unless Illustrator allows you to change the
screen units. Inkscape assumes that the default resolution is 90 dpi.

The size difference between the two files is confirmed. The bounding
boxes
for the two .svg files are given below.
Illustrator - width="194.284px" height="75.238px"
Inkscape - width="242.855" height="94.04725"
The ratio of the sizes is exactly 1.25 which equals 90/72, which equals the
size ratio of a point to a pixel. It looks as though Inkscape has probably
assumed that the original dimensions were given in points, and has probably
converted them to pixels by multiplying by 90/72, which is a reasonable
thing to do. (However, I know nothing about Illustrator, so I don't know if
the native units in Illustrator are points or not.

I believe you are confusing 90 with 96. 96 pixels / inch is the
reference standard given in CSS3
(
http://www.w3.org/TR/css3-values/#reference), *though*, it's a
'relative' value that is listed as being defined by an angle of vision,
96 is the most common value associated with pixels (happening to be 1.5
* the size of an ADOBE (and web standard) 'point', which is defined as a
as a physical unit in HTML as 1/72nd of an inch.
The value of of dots/inch in a photo or Illustrator diagram is
settable on a per-image basis. It's initial value will come from the
value set in any template you choose (usually 72dpi).
The default dpi in inkscape is set in its preferences under
import/export. There you can set the default dpi you wish to use. That
the product ships with a default of 90 would seem to be a bug as it
doesn't correspond to any standard that I know of (72 or 96 or 100 would
have made more sense, with 100 being from the nearest fixed-font size
under the X-window system as well as being metric-like and easily
subdivided).
Hopefully if you set your Import/Export value to 72 or 96 (72 seems
like such low resolution -- it's a very old standard, suitable for type
sizing, but not pixels/inch. Remember, print is anything from 150-300
dpi. 72 or 96 would look pretty bad in print. Without Truetype,
opentype or similar font-smoothing technology, 96dpi doesn't look very
good on the screen, either.
