Imperial to Metric Weight Conversion table

Before we start let me just say whoever came up with the imperial to metric weight conversion scale should be kicked squarely in the nuts. I mean, 1oz is 28.349 grams. 28.349? Why not 25 or 30? To be honest i use a 1oz=25g scale which makes it easy to work out but for those obsessed with the odd three and a wisp grams - which isn't going to make a jot of difference until you get to 9oz and again until you get to 18oz and so on in multiples of 9oz - here is the beast, worts and all. 28.349 grams! I've still ignored the .349!
