Calculating Value of Gold by Weight: What You Need to Know

How Heavy Is Gold?

Gold is heavy because each gold atom weighs 196.96657 u, but it is usually measured in troy ounces. A troy ounce contains 31.1 grams or 0.07 pounds. Gold has a high peak density of 19.32 grams per cubic centimeter, which makes it heavier than other metals like iron (7.87). This is caused by the heaviness of each atom in gold. You will not feel that heaviness in a gold fleck you find in Illinois Creek, but if you’re talking about amounts of gold jewels and coins and bars, then weight becomes a completely different story.

What Is a Gold Bar?

A gold bar is a piece of metal that is made to be like gold, and people can buy it. It has to be made in a certain way and then labeled and recorded.

Gold bars that are made by pouring the molten metal into a mold may be called ingots. Bars can also be made from sheets of gold that have been rolled and stamped with a die. The standard gold bar that is used by central banks and traded among dealers is the 400-troy-ounce gold bar. It weighs 12.4 kilograms or 438.9 ounces. The kilobar, which is 1000 grams in weight, and a 100-ounce gold bar are the bars that are more manageable. They are often used for trading and investments.

The price of these bars is very low when you trade them. The worth of the gold that they contain is not as important as the price. So, this is a good way for banks and traders to send money or trade to each other. Most kilobars are flat. Some investors like brick-shaped bars, but Asian markets prefer gram gold bars. Popular sizes include 10 grams, 100 grams, and 1,000-gram bars.

The History of Gold Bars

The Gold Standard

Investopedia defines the Gold Standard as follows:

A gold standard is a system where money and paper money has a value linked to gold. Countries agreed to convert paper money into a fixed amount of gold. A country that uses the gold standard sets a price for gold. It purchases and sells gold at that price.

Gold is a way that some countries used to show their money was worth something. They would use the gold and paper money to trade with other countries. People who want to trade in gold for money can do so with paper and coins with symbols. These are called dollars. They are a way to control the economy by preventing inflation.

The United States stopped using the gold standard in 1971, and no other country is using it now. The fiat system replaced the gold standard for most countries. This system works by having individual governments control their currency. This system is in place in the United States today.

Even though no one is using the gold standard anymore, many people still own gold. People who own gold for investment purposes hope that it will increase in value.

Because the United States used to have the gold standard, we own many gold bars. They are in our country, and they are like when you see them in movies. The gold reserves are kept safe in vaults. They are at the United States Bullion Depository, which is in Fort Knox, Kentucky. The United States Department of the Treasury owns them.

Gold was used as a measurement system. You can exchange money for gold. The value of the money changes if the price of gold changes. The gold standard is when society agrees that money is worth something. Society agrees that the money they spend and earn can be traded for gold.

Gold is a good way to measure the value of money. Gold has been used for centuries, and it may not be as popular now. Gold is also sometimes bad because it can be stolen or lost.

Fort Knox

Fort Knox is a place that has lots of gold. It’s in Kentucky, and it’s an Army post. Fort Knox was made so people could feel safe there with the gold. The gold was moved there from New York City and Philadelphia so that people couldn’t steal it.

The United States Postal Service carries gold from two cities to Fort Knox. They carried it by land because the gold bars were too heavy for planes. Fort Knox has been one of the most secure places in America since then.

Many important documents stayed safe during World War II. They were in Fort Knox. The Constitution, the Declaration of Independence, and other important documents were there too. Fort Knox has lots of security devices, like cameras and alarms. And there are even landmines outside the property. Radars can see all around the place, too.

The President of the United States can’t go to Fort Knox. So far, Franklin Delano Roosevelt is the only president who has been to Fort Knox.

Fort Knox currently holds 10 million pounds of gold. If all of the gold in Fort Knox were in bars, there would be 367,500 bars. The value of all the gold at Fort Knox is over 250 billion dollars.

Weight and Dimensions of One Gold Bar

Gold is hard to find in large quantities. Many gold bars are small. Gold is a common investment commodity, so many people buy it. Most people do not buy a regular bar of gold. They buy bars that are smaller than a paperclip or bigger than a smartphone.

A bar of gold that is the size of a smartphone weighs about one kilogram. This bar is worth over $57,000. This is worth more than a standard gold bar which weighs about 400 troy ounces (over 11 kilograms, or 27.5 pounds) and is worth over $700,000.

Few people have gold bars at home. It is difficult to invest in gold with one bar because it is expensive. Some people have many small bars. If they are interested in investing, they will have many coins, not just one standard-size coin. We will talk about this behind time in the article.

Cast or Minted

Investing in Gold

No countries use gold as the standard for their money. But gold is still valuable because it is a precious metal. You should buy some or invest in a gold mine to diversify your investment portfolio.

Some people think that currencies might go back to the gold standard during times of economic turmoil. That would not be a bad thing because you would have some gold around. But this is unlikely to happen.

What to Buy

If you want to acquire gold for your investment portfolio, it is best to buy smaller bars or coins at a lower price. That way, the price will be more affordable, so you can diversify your investments.

It is better to sell smaller amounts of your gold supply because it gives you more liquidity. If you need money, you can sell only part of your gold supply in the future. For example, if you place all of your gold investments into one bar of gold, you wouldn’t be able to sell half of it. It’s better to buy small bars and coins.

Gold bars and coins are close to pure gold. They have a serial number on them, so you can tell it is real and not fake.
