but because being light, you still need a fair load to get
anywhere.

Aluminium is the same weight per kilo as copper or brass.

:-)

Even on the moon too.


Being pedantic the mass will be the same but the weight, which
should be measured as a force in units such as Newtons, would be
somewhat less.

I was under the impression that a kilo of aluminium will be the
same weight as a kilo of copper or brass _anywhere_.

It's just on the moon they'll both weigh about a sixth of what they
do here.

With respect you've missed the difference between mass and weight.

Mass is independent of gravity and measured in kg. Weight is wholly
dependent on gravity and measured in Newtons. Weight has never been
formally measured in kg

Others might consider its use as a unit of weight in UK and EU
legislation pretty formal.

Which just goes to show how clueless law writers and their teachers are.


Then please share your suggestion for practicable definitions of weights
for the purposes of "weights and measures" legislation which don't
equate it with mass.Â* And FTAOD that's practicable including taking
account of the variation in gravitational acceleration from place to place.

Simply by describing objects measured by way of by mass and not weight.
We have volumes measure in unit of pints or litres, so why not measure
mass in terms of units for 'mass'?
