Yeah, yeah, I know. Parochial and childish, but it is what it is. I personally use both systems interchangeably.

So at the present time, the "English" measurements are used in, uhh, Liberia, Myanmar and the US. Runnin' with the Big Dogs!

Mark and 'Anonymus': the metric system is used in all of science, check it out. Remember the failed Mars shot some 30-40 years ago? The clear cause of conversion factor errors. Dan, don't forget your metric tool set when flying your beautiful Stemme!
