I'd like to digress for a moment to showcase this fine achievement in canadian technology, the Butter Ruler (tm). I know down there in the states, packages of butter have markings on the wrapper that tell you how much butter is there. However, these measurements are not strictly precise, due to the fact that the butter may not be perfectly centered in the wrapper.
Here's where Canadian genius steps in, with the Butter Ruler (tm). By placing it against your butter, you can accurately gauge measurements. No more getting 1.0245 cups of butter when you only intended to use 1. Butter Ruler (tm) sells for $69.95, and comes with a fashionable rear mountable magnet, allowing you to store Butter Ruler (tm) on your fridge.
