yes, that's about true.

it's a volume.
one liter water (specific gravity == 1kg/dm^2)
has a mass of 1 kg. (at some very exact physical conditions).
this one liter will weigh 9,81N somewhere on earth, and zero N in space.
(but it will still be 1 liter.). the scales on earth are calibrated to
display
the mass (in kg or something, not N).
The liter is a unit of volume, 1 liter beeing 1 cubic decimeter, or 1000
cubic
centimeters, or 1000 000 cubic millimeters, or 0,001 cubic meters.
If you fill a "liter" of flour in a bottle with one liter volume
or a liter water doesn't matter. the flour is compressible so the mass
will change.
The liter is usually only used with liquid things, but it IS a voloume
measurement and thus may also be used for other stuff if you insist.

We do not use the liter for any non-fluid stuff.

I don't know what ounces are, and i don't know the difference between dry
and liquid ones.
to make any sense there shouldn't be a difference in my opinion.

volumes and mass are linked by specific gravity (density). density =
mass/volume.
Weight is the force you get when you accelerate mass, nothing more.
on earth it is about 9,81m/s^2, (on poles a bit more i think).
There is no cross between volume and weight, there is a relationship,
nothing more.
The problem is much more that all scales display mass, but they "weigh"
stuff.
(they measure the force of gravity pulling the item down).
In daily life you won't need to know about the "weight force" of anything,
you use the mass and trust that all scales are calibrated correctly and
you don't move away from the earth's surface.

yes... but i think the s.g. of silver is about 10,
so even if in this 0.1kg (100g) is 100% silver you get 10ml.
most likely it will NOT be 100% silver, and with the other ingredients
most likely beeing around s.g. 1 it must be between 100ml and 10ml.

I don't care about this bloke. He ought to learn SI and have a easier life.

You are american(?), so you can write liter.
if you were british you would need to write litre.
(In german it is liter and i won't use the british spelling for sure.)
