Hamilton supported Jefferson's proposal for a "decimal" system for currency.
Jefferson proposed a decimal system for weights and measures that was not based the odd English systems, or on French metric system "standards" (which had not yet been established). Jefferson's proposal was dropped due to other "national" distractions. Jefferson probably based his ideas on previous ideas/proposals made by the genius/patriot, Benjamin Franklin (and others).
There was a "Metric Act of 1866", but, by then, industry ruled - it did not want to change "standards" that would be expensive to conform-with/change-to.
Nonetheless - I join coilover in calling the English systems "crappy".
