Measure for Measure

There’s a reason why the metric system system remains so universally unpopular and that is its damnable inconsistency. Look here: their inch, which they call the centimeter, is less than half the length of the conventional unit while their yard is three inches longer than normal. Confused yet? I propose to simplify the metric system in order to make it easier to understand and use. After my revisions, each metric measure will be exactly one half of the unit it imitates. Thus, the kilometer will equal exactly 0.5 miles and official standard human body temperature will be 49.3 degrees Celsius.
