Maya Modeling :: NURBs And Polygons Not On Same Scale?

i was creating a simple character(blobs withen blobs). It was going pretty good until i camme across an issue that i can't seem to fix. I first had his neck as a nurb but i realized to do what i wanted i would need to deleted a couple faces so simple create a polygon the same size and shape. So i draged the nurb over clicked create polygon and i made it. The issues was that i can not seem to get them the same size i went to the channel box and typed in the same numbers for size. It was similiar but, was off the entire object was too big. I tried extruding it to match the same rough height and i got that nurb was on a scale that was about 1.626 times larger this. I forgot to mention that i am running maya 2014 student edition.
