So OG assumes the imported SVG is in points but the units in the SVG are metric (and my drawing is in feet, of course!).

So if I import the SVG, what scaling do I have to apply (percentage increase in size) for converting and having image appear correctly sized? From point to meter I see it is 2835 points in a meter, then it is 3.28 feet per meter and my scale is 20 feet per inch. So would it be:

2835 / 3.28 / 20? When I was testing this out (did not finish) it seemed something around 250-275% enlargement of the SVG was pretty close but I would really like to figure out the exact conversion factor.
