Not any easier than with U.S. or Imperial units. BTW, a few years

Naw, it was because some idiot provided some of the terms in
metric instead of proper units.


It wouldn't have happened if they had used proper (i.e. _metric_ ;-) )
units consistently.


Huh?? "Meter" isn't any more similar to "gram" than, say, "foot" is to
"ounce". If you refer to the common prefixes, this is the big
_advantage_. If you know that a kilometer is 1000 meters, you
immediately know that a kilogram is 1000 grams, a kilovolt is 1000
volts, etc. No need to memorize all the factors to convert inches -
feet - miles, ounces - pounds, and whatever.


But nobody weighs things in "grams", it's always "kilograms".


Nonsense. It depends - of course - on the size of the items.


Nor do the measure things in "meters" (as was stated concerning
building a house) they measure in "milimeters".


And so what? The OP said metric units had "usability
problems (like similar sounding names for various units)". Neither
"meter" nor "millimeter" sound similar to other non-distance metric units.
