Answer 2

this question sounds mighty suspiscious why you need to find something weighing a gram, but you could get a piece of paper, find out what gsm (grams per square metre) the paper is, then just cut the paper to the right size for it to weigh a gram, eg if you had a piece of A4 paper that was 80gsm, its 21 x 29.7cm = 573.3cm2 = 0.5733m2

if its 80gsm then we do 0.5733 x 80 = 4.5864g

now we need to scale the paper down by the right amount so that it weighs one gram.

if we choose the long edge of the paper at 29.7cm to measure down, we perform:

29.7 x 1/4.5864 = length of paper to measure from the long edge (to keep, the rest past this gets thrown away) = 0.37125cm

so if you cut an 80gsm piece of paper down to about 0.37cm by 21cm it should (give or take a minor amount of weight) weigh one gram.

any two edges that multiply together to give the same answer as 0.37 x 21 will work too, like 2.85 x 2.85 cm Paperclip
