Ruler doesn't measure out to an actual true ruler distance although it gives the values in the ruler bar.

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Draw a rectangle on the canvas with the ruler turned on.

What is the expected output? What do you see instead?

If I was to draw a shape and zoom to 100%, I would expect that 

In what browser did you experience this problem? (ALL, Firefox, Opera, etc)

ALL

In what version of SVG-edit does the problem occur? (Latest trunk, 2.5.1,
etc)

TRUNK

Please provide any additional information below.

I would expect to be able to draw a shape on the screen and with the ruler 
turned on, have it scaled exactly as it would to a real ruler distance so if I 
measured the length/width with a ruler, it would be the exact length/width.  
I'm looking for a solution/suggestion so that the measurements are more 
accurate.  I'd appreciate any help on this.  Thanks.

If I understand correctly, what you want is that at zoom 100%, you put a real 
ruler on the screen and it would match the dimensions of SVG Edit's rulers. To 
my knowledge, no professional graphic design software is capable of  doing 
this. To achieve this you would need to know the actual pixels per inch of the 
screen, and even then there's a lot of edge cases (what happens when you have 
two monitors with different ppi's, and the window is stretched across both 
monitors?).

If you go into the menu > editor options you can set the dimensions to inches 
or any unit you'd like. It will be more similar to a ruler, but still not quite 
there (depending on the ppi's of your screen).
