gold price per gram
Gold is one of the most valuable precious metals and is widely used in jewelry, coins, and other decorative objects. The value of gold is determined by its purity and weight. If you are interested in buying or selling gold, it is important to know how to calculate its worth accurately. In this article, we will explain how to calculate the worth of gold, taking into consideration its purity and the cost of melting the gold.
Understanding Gold Purity
Gold purity is measured in karats (K) or fineness. 24K gold is considered pure gold and is made up of 99.9% gold. 21K gold is 87.5% gold, 18K gold is 75% gold, 14K gold is 58.3% gold, and 9K gold is 37.5% gold. The remaining percentage is made up of other metals such as silver, copper, or nickel, which are added to increase the metal's durability and strength.
Calculating the Worth of Gold
To calculate the worth of gold, you need to know its weight and purity. The price of gold is quoted in ounces or grams. In most cases, the weight of gold is measured in grams, and the price is quoted per gram.
Step 1: Determine the Weight of Gold
The first step is to determine the weight of the gold. You can use a digital scale to weigh the gold accurately. If you are buying or selling gold, it is essential to have an accurate weight of the gold.
Step 2: Determine the Purity of Gold
Next, you need to determine the purity of the gold. This can be done by looking for markings on the gold, such as 24K, 21K, 18K, 14K, or 9K. If there are no markings, you can take the gold to a jeweler, who can test the gold and determine its purity.
Step 3: Calculate the Value of Gold
Once you know the weight and purity of the gold, you can calculate its value. To do this, you can use an online gold calculator or use the following formula:
Value of Gold = Weight of Gold (in grams) x Purity of Gold x Price of Gold per Gram
For example, let's say you have 10 grams of 18K gold. The current market price of gold is $60 per gram. To calculate the value of the gold, you would use the following formula:
Value of Gold = 10 grams x 0.75 (purity of 18K gold) x $60 per gram
Value of Gold = $450
In this example, the value of the 18K gold is $450.
Cost of Melting Gold
There is also a cost associated with melting the gold. When gold is melted down, it needs to be refined to remove impurities, which can add to the cost. The cost of melting gold can vary depending on the refinery and the purity of the gold. Typically, the cost of melting gold is around 1-2% of the total value of the gold.
