most people would also want to own a tonne of gold. but there is only 170,000 tonnes of gold in the world.. so grams and ounces have to suffice, much like microbitcoins and satoshi's will have to suffice
Most people measure the gold in either ounces or grams. So if we calculate based on that, then there are some 5,465,500,000 ounces of gold, or some 170,000,000,000 grams of gold. That is almost 25 grams for every human being on this earth.
