Can you re-phrase the question and provide more info?
1000% is 1000%. Cannot be directly converted to pixels.
Hi, Sorry I meant 100% NOT 1000%. I mean If I create a table in dreamweaver thats 100% in size, then make a banner in photoshop how mainy pixels in width does the banner need to be to fit in my table of 100%.
Thanks, Hope you understand
How long is a piece of string?
It depends on the size of your visitors viewport. If the viewport is 800 pixels wide, then it would need to be 800 pixels. If it is 1024, then 1024.
Percentages are a relative term based on the end user's browser viewport. In short, the viewport width could be almost anything at all because people don't always keep their browsers maximized to full screen capability. And even if they do, you can't be sure that your end user's display settings are the same as yours.
IMO, Fixed-width, centered layouts are the most convenient to work with. I think that's why so many web designers use them. The trick is finding the "right width" in pixels for YOUR target audience. For most desktop and laptop users, 970 to 1200px is probably a good range. For mobile devices and handhelds less than 660px.
This handy tool from Google Labs may help shed light on which viewport widths most people can see.

As the others have stated, that cannot be calculated.
% is relative. Pixels are absolute units of measurement.
100% of 800 pixels is 800.
100% of 1024 pixels is 1024.
