OK... anyone got pointers to a credible table relating imperial card/paper weight measures (which seem to vary depending on what paper it is) to a) eachother and b) gsm? Personally, I like gsm, mainly 'cos it's universal and applies to any size of paper. Also, in Europe, the paper tends to be sold that way. I've currently got some A4 220gsm white card which will go through my printer, which is fine up to a point, and obviously the normal 80gsm plain paper. All this is well and good, but doesn't help when a kit for printing says "print on 60-110lb paper" or somesuch. and yes, I did google for it.
