Are you using MRTG in native mode, or with RRDTool - and if RRD mode, then which frontend are you using?

Whichever you use, normally you'll only get at most 3 or 4 significant figures shown; you could add the appropriate options to prevent the 'k' etc suffixes which should give you exact figures but how to do this depends on which frontend you use or which mode MRTG runs in.  Also if the numbers are too big it can cause layout issues, particularly with RRD 1.0.x or even RRD 1.2.x
