Your UV-Map coordinates are between 0 and 1 in most of the cases. Values below 0 or above 1 are get either clamped, repeated or whatever depending on your texture coordinate settings. There is no possibility to get from 0-1 values to your real texture size in pixels. or did I understood the problem wrong?
