Gold is a heavy metal. It has a density of 19.3 g per cubic centimeter. Let's compare it to iron, one of the most regularly utilized metals, to have a better idea. If you have a 1 kilogram block of iron, a gold block of the same proportions will weigh around 2.45 kg. A car engine block is made up of about 50 percent iron and 50 percent copper. That means the gold block would weigh about 1.13 kg. In terms of value, gold is very expensive. One troy ounce of gold costs about $1130 at current prices. Copper is more affordable - a troy ounce costs about $60-80. But gold is much heavier than copper; therefore it requires more energy to move it. The average human body weighs about 60 kilograms or 132 pounds. That means if you were to fill your stomach with gold coins, they would weigh about as much as you do. This isn't really possible because coins don't melt in your mouth or anything like that but the concept is interesting. It's important to remember that gold is a precious metal. There are other more economical ways to store value such as savings accounts or credit cards. Gold is best saved for investment purposes only.
