Afterall, the metric system is undoubtably more superior and efficient.
Oh were it so simple.
The fact is that foot-pound-second is a perfectly rational system of units that works just as well and consistently as kg-m-s.
The world is effectively divided into two - those using the old Imperial system, and those using SI, whilst in reality both use lots of bastardised units like kgf or cm that confuse the issue. Personally I think that everybody should learn both.
The arrogance of Americans thinking they don't need to learn SI, and Europeans who think that Imperial is obsolete and can be ignored does nobody any good. Just be thankful that for the first time in human history there are only two major systems to learn - 200 years ago every country had it's own, often every town or every factory.
