Gold Purity Calculator helps you calculate the purity of gold using Karat rating.
Gold holds a special place in the hearts and traditions of Bangladesh. From ornate jewelry to financial security, gold plays a multifaceted role in the lives of many Bangladeshis. Understanding the purity and weight of your gold jewelry is not just a matter of sentiment but also of financial significance.
To assist you in this endeavor, we present the "Gold Purity Calculator," a tool designed to align with the local standards of measurement and help you make informed decisions when it comes to your precious gold possessions.
Determining the purity of your gold jewelry in terms of a percentage is a straightforward process. Follow these steps:
Input Karat Value: Begin by identifying the karat value of your jewelry. This information is often engraved or imprinted on the piece itself. For instance, if your jewelry bears the mark "18K," use the number "18" in your calculation.
Calculate Purity Percentage: Divide the karat value by 24, representing the maximum karat value for pure gold, and then multiply the result by 100. This computation yields the purity percentage. As an example, for an 18-karat piece: (18 / 24) * 100 = 75%. Hence, your 18-karat jewelry consists of 75% pure gold.
Determine Pure Gold Weight: To ascertain the quantity of pure gold in your jewelry, multiply its weight in grams by the purity percentage. For example, if your 18-karat gold ring weighs 10 grams, calculate it as (10 grams * 75%) = 7.5 grams of pure gold.
Dealing with varying units of measurement for gold requires knowledge of these conversions:
1 troy ounce ≈ 31.1 grams.
1 standard ounce ≈ 28.34 grams.To convert your gold weight from grams to ounces:
Standard Ounces: Divide the weight in grams by 28.34. For instance, if you possess 10 grams of gold, it equates to roughly 10 grams / 28.34 = 0.35 standard ounces.
Troy Ounces: Divide the weight in grams by 31.1. Using the same example, 10 grams / 31.1 = 0.32 troy ounces.
Simplifying these calculations for your convenience, we offer the Gold Purity Calculator tailored for Bangladeshi users. Just input the karat value and weight in grams, and the calculator will furnish you with the purity percentage, pure gold weight, and the weight in both standard and troy ounces.

The formula for calculating the percentage purity of a substance is:Percentage Purity (%) = (Pure Substance Mass / Total Mass) x 100
Pure Substance Mass is the mass of the pure or desired substance in the sample (usually in grams).
Total Mass is the total mass of the sample (usually in grams) that includes both the pure substance and any impurities or other substances.
You can use this formula to determine the percentage purity of a chemical compound or substance by measuring the mass of the pure substance and the total mass of the sample containing the substance and any impurities. Then, plug these values into the formula to calculate the percentage purity.
Gold is refined to 99.99% purity through a series of chemical and metallurgical processes. The process of refining gold to such high purity typically involves several steps:
It's important to note that the exact refining process can vary depending on the source of the gold (e.g., from mining, recycling, or scrap jewelry) and the specific impurities present. Refining gold to such high purity is a meticulous and precise process that requires careful control of various parameters to achieve the desired result.
In the context of gold jewelry, "KDM" does not refer to a specific type of gold, but rather it is a hallmark used in India to indicate the type of soldering or welding technique used in the jewelry manufacturing process. KDM stands for "Cadmium (Cd) Mercury (Hg)," which were traditionally used as soldering agents in gold jewelry making.Here's what KDM signifies:
However, the use of cadmium and mercury in jewelry making has raised health and environmental concerns due to their toxicity. In response to these concerns, regulations have been put in place in many countries, including India, to restrict or ban the use of these substances in jewelry production.
Today, modern jewelry manufacturing processes avoid the use of cadmium and mercury, and safer soldering techniques are employed. As a result, the KDM hallmark has become less common in the jewelry industry.
When purchasing gold jewelry in India, it's important to look for hallmarks that indicate the gold's purity (such as 916 for 22-karat gold) and the jeweler's certification mark rather than focusing on the KDM hallmark, which is no longer a reliable indicator of jewelry quality or safety.
Pure gold, often referred to as 24-karat gold (24k), is considered to be 99.99% pure. This means it contains virtually no impurities.
To calculate the weight of a certain amount of 24-karat gold in grams, you simply need to know the weight in a different unit (such as ounces or troy ounces) and convert it to grams.Here are some common conversions:
So, if you have a certain weight of 24-karat gold in troy ounces, you can multiply it by approximately 31.1035 to find the weight in grams. Similarly, if you have the weight in regular ounces, you can multiply it by approximately 28.3495 to find the weight in grams.
For example, if you have 1 troy ounce of 24-karat gold, it would be approximately 31.1035 grams. If you have 1 regular ounce of 24-karat gold, it would be approximately 28.3495 grams.
Keep in mind that these are approximate conversions, and the exact value may vary slightly depending on the source and rounding used for conversions.
To calculate the density and purity of gold, you'll need to measure both its mass and volume, and then use the formula for density. The purity can be determined by comparing the density of the gold object to the density of pure gold, which is known. Here are the steps to calculate gold density and purity:
Keep in mind that this method provides an estimation of purity and may not be precise, especially for gold jewelry that may contain other metals as part of the alloy. For extremely precise purity determination, more advanced techniques such as X-ray fluorescence (XRF) or fire assay may be used by professionals.
Also, note that gold can have different densities at different temperatures, so it's important to perform these measurements at a consistent temperature, typically at or around room temperature.
