I think we got into the generalities of the atmospheres of various

Only if you weighed 2115lbs on Earth.

You multiple by 2.36 to get the right figure.

Do you really have to get every last thing wrong?

I'm going to have to reveal something about my apparent ignorance in
physics here:

I'd initially thought this page rather suspect since it claims my weight
on Saturn would be almost the same (106%) as my terrestrial weight,
despite the fact that I was under the impression that Saturn was around
100 times more massive than Earth.

So, a quick trip to Wikipedia reveals I'm even more confused than I
thought. It confirms that the mass of Saturn is 95.152 earth masses, but
also claims the surface gravity is 0.914g.

What am I missing here?

Please disregard my senior moment above.

I realised that I needed to take the difference in planetary radii into
account just as I was hitting the 'post' button.
