America is moving towards the metric system, one inch at a time //

will not do it. Read Measuring America and it will explain to why it will never fully switch to metric. State DOT's have tried. and it always ends up back with the Survey foot. //

@Adam Smith THIS! Few people actually get this. Metric beats imperial when converting between units, but in MOST day to day life, you don't care... even in the SAME vector. Do I REALLY need to know how many feet it is between New York and Washington? So... does it REALLY matter that there are n feet / mile? In Canada, highway exits put signs out as 1200m and 400m. In the US, they do ¾ mile and ¼ mile... and there may be a case for keeping the units the same for faster processing.
They're both JUST as understandable. //

The thing is you almost never do any arithmetic in aviation where the units would matter. Thus it does not matter what units you use. You just know that your flight level is X or Y units, no matter. Also the different units may be safer because they also imply what is being measured or indicated. And the change over to metric would surely cause a lot of accidents before it would be through. So safety first.
