[Inkscape-user] Making Screen Units and SVG Units the same

People,

When I create a new image, I get a page that, in Landscape mode, is 800 units wide and 600 units high. I know that the origin for the SVG y-axis is at the top-left of the screen and the positive direction is down and the reverse is the case for the Inkscape y-axis and I am not concerned for this exercise about printed output. I just want the absolute units on the screen to correspond to the absolute units in the SVG file that Inkscape produces - is this possible? (I couldn't find anything in the program or Googling . .)

Thanks,

Phil.
