In normal everyday usage, weight is not the force due to gravity, it's the
amount of matter in the object you are referring to (aka mass). Check the
label on any product at the grocery store, it lists the net weight of the
product, not the mass. Only in engineering and scientific circles is there
any distinction made between the two terms, and that's only because some
scientist in the distant past was too lazy to come up with a new term for
"the force due to gravity". Long before spring scales were invented,
everything was "weighed" on a balance by comparing it to known standard
weights. A balance does not measure force. You can be certain that any legal
document that refers to weight is not referring to any kind of force.

We'll just have to wait and see how the lunar courts choose to
interpret Part 103! The moon will become the new home for the "fat"
ultralights

On second thought, do we really want lawyers on the moon? That could
be opening the door to frivolous product liability lawsuits. Will
manufacturers be held accountable when, I'm just supposing here,
their airplanes malfunction without an atmosphere?
