What is the size of the sheet you can get from 1 gm gold?

Answer 1

there is a lot more to this, gold can be flattend to about 0.00001mm, so thin that even light can pass through it, put into a string, you could make a string of about 3,000 meters. one standard gold leaf is 85 mm x 85 mm (18 to) 23 grams per 1,000 leaves 1000gr = 43,478 leaves of 85 mm x 85 mm one leaf is this 0.023g, with 1g of gold you got 1000th of the above: 4.3478 leaves of gold, about 31,412.86 sq mm (0.03141286 sq meters or 314 sq cm) i dont know what your planning but you could also just buy it online, its easier than slamming your gramm flat for hours
