I would personally prefer to call these units neo-Napoleonic or second hand
metric units to-day. Napoleon is often wrongly credited with spreading the
metric system over Europe, while in fact he almost brought it down. It was
under Napoleon that for the first time old units were defined in terms of
metric ones, and the USA did that again in 1893.
I do not like the prefix 'metric' for USA and UK units.
I would go one stage further and say that the 'metric foot' is seen as 30cm
and the 'metric pound' is seen as 500g which is quite a deviation from the
real measures.
I think I can understand why a few try to claim that imperial is really
actually metric underneath (ie. the "you're already using metric" notion)
but the average person would actually see metric and imperial units as those
that have a conversion factor.
