I'm used to our goofy system of measure, just as all of us Uhmericans are more or less (from the looks of it, mostly less) used to that craziest, most irrational and arbitrary of languages, English. P.S. Because of this I will probably always have to use conversions to English units for weights and measures, simply because of their overwhelming dominance in common usage.
Speaking (PUN!) of which, since the world is deciding on the most rational system of weights and measures, why would the world also decide on the most irrational language?
