How to Convert Gold from 24 Karat to 21 Karat
There are two methods for converting gold from 24 karat to 21 karat. We will explain each method in detail:
Method 1: Converting Gold to 21 Karat
- Start by knowing the current price of an ounce of gold according to the global stock exchange. Let’s assume it’s approximately $2,000 USD.
- An ounce of gold is typically 24 karats and weighs around 31.1 grams.
- Divide the price of an ounce of gold by its weight to determine the price of one gram of 24-karat gold. In this example, it would be 31.1 / 24 = $64.30.
- Multiply the price per gram of 24-karat gold by 0.875, resulting in $56.27, which is the price per gram of 21-karat gold.
Method 2: Converting Gold from 24 Karat to 21 Karat
Here’s the second method for conversion, explained in the following two steps:
- Apply the first method to calculate the price per gram of 24-karat gold, which in the example above is $64.30.
- Multiply this figure by 21 and then divide the result by 24. So, $64.30 x 21 = $1350, and then $1350 / 24 = $56.25, which is the price per gram of 21-karat gold.
