Not to further muddify things at all, but I've known several British
people who tell me their weight in "stones" - something I've never seen
in a Physics book. Does anybody know anything about this unit? Is it
weight or mass? The "British" unit of "slug" only ever seems to appear
in American Physics books. Check out http://www.speckdesign.com/Tweight.html for more weight/mass conversions
than you ever cared to see. This calculator translated my weight (200
pounds) to 14.3 stone, though I think calling myself 3.5 million carats
has some appeal!
