I think they try to avoid "weight" altogether. It's a really nasty ambiguous word which can be taken to mean "mass" or "gravitational force" depending on who's using it. There might be an official meaning for it, but it's so widely mis-used that it's practically useless. > > >Blokes heaving on spanners here on Earth can get by with saying >that 1 newton of force == 1 kilo of force. No. It's a bit less than a tenth of that. Cheers, Colin.
