at the begining when u created ur account it showed u a banana and asked if this was 25 cm or inch .. from what u say u answered inch .. everything is in inch then .. the thing ur reffering to on the left is ur excitement ex: 60/125.... the bar with number u see on the left of the screen is just a ruler that dont realy mather.
as for the drugs u buy at the pharmacy its measured in excitement ...so if ur max is 125 just buy what u need without doing overdose or u risk hospital.
hope that answer ur question ... if not just clarify and ill check back eventualy
