convert 24 carat gold to 18 carat
Hello. Welcome to solsarin. This post is about “convert 24 carat gold to 18 carat“.
Fineness
The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of fine metal therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver oins in the past, contains 90% silver and 10% copper, by mass. Sterling silver contains 92.5% silver and 7.5% of other metals, usually copper, by mass.
Various ways of expressing fineness have been used and two remain in common use: millesimal fineness expressed in units of parts per 1,000 and karats used only for gold. Karats measure the parts per 24, so that 18 karat = 18⁄24 = 75% and 24 karat gold is considered 100% gold.
What is 24-carat gold? How will you convert it into 18-carat gold?
Hint: 24-carat gold is 99⋅9pure gold which has no other metal impurities added in it. It is bright yellow in appearance. 18-carat gold has copper or silver mixed along with gold. 24-carat gold can be converted to 18-carat gold by alloying it with copper or silver. This is done to increase its hardness.
Complete answer:
The word carat means parts per 24. 24-carat gold contains all 24 parts gold so it is the purest gold available. It is very soft because making jewelry with it becomes difficult as it is more prone to scratching and wear-tear. So it is converted to some other carat gold to increase its hardness so that it becomes efficient for making jewelry. 18-carat gold contains 18 parts per 24 i.e. 18/24=75% gold and 25 alloy of silver or copper or we can say 18 parts pure gold and 6 parts alloy mixture.18-carat gold is harder than 24-carat gold due to which it is more suitable for jewelry.

Addition of other metals makes the gold more durable. Since 24-carat gold is purer than 18-carat gold so it is more expensive.
One way to test gold’s purity is by holding it next to a magnet. Gold is not attracted by magnet so if 18-carat gold jewelry sticks to the magnet then it indicates that there are fewer parts per gold and other magnetic materials are added more which makes the gold impure.
Note:
Carat is a unit of purity for gold. Jewelry is expressed in ‘k’ or ‘kt’ and it is stamped in small numbers on the jewelry pieces. The addition of metals to 24-carat gold provides it more strength and durability and it is then available in 10k, 14k, 18k and 22k depending on the parts of gold and metals added to it. 18k gold is quite high in demand because it provides more durability and has a golden rich appearance. It is quite used for making wedding and engagement rings.
Solution
24-carat gold is pure gold. Pure gold is very soft and not suitable for making jewllery. Therefore, to increase its hardness, it is alloyed either with copper or silver. 18-carat gold is prepared by alloying 18 parts pure gold with 6 parts of either copper or silver.
Solid Pure 24k Gold Amounts
This calculator tool is based on the pure 24K gold, with Density: 19.282 g/cm3 calculated (24 karat gold grade, finest quality raw and solid gold volume; from native gold, the type we invest -in commodity markets, by trading in forex platform and in commodity future trading. Both the troy and the avoirdupois ounce units listed under the gold metal main menu. I advice learning from a commodity trading school first. Then buy and sell.) Gold can found listed either in table among noble metals or with precious metals.

Convert gold measuring units between carat (purity of gold) (kt – K) and grams (g) of gold but in the other direction from grams into carats (purity of gold).
Precious metals: gold conversion
This online gold from kt – K into g (precious metal) converter is a handy tool not just for certified or experienced professionals. It can help when selling scrap metals for recycling.
Other applications of this gold calculator are …
With the above mentioned units calculating service it provides, this gold converter proved to be useful also as a teaching tool:
1. in practicing carats (purity of gold) and grams ( kt – K vs. g ) exchange.
2. for conversion factors training exercises with converting mass/weights units vs. liquid/fluid volume units measures.
3. work with gold’s density values including other physical properties this metal has.
International unit symbols for these two gold measurements are:
Abbreviation or prefix ( abbr. short brevis ), unit symbol, for carat (purity of gold) is: kt – K
Abbreviation or prefix ( abbr. ) brevis – short unit symbol for gram is: g
One carat (purity of gold) of gold converted to gram equals to 0.21 g
How many grams of gold are in 1 carat (purity of gold)? The answer is: The change of 1 kt – K ( carat (purity of gold) ) unit of a gold amount equals = to 0.21 g ( gram ) as the equivalent measure for the same gold type.

In principle with any measuring task, switched on professional people always ensure, and their success depends on, they get the most precise conversion results everywhere and every-time. Not only whenever possible, it’s always so. Often having only a good idea ( or more ideas ) might not be perfect nor good enough solutions. Subjects of high economic value such as stocks, foreign exchange market and various units in precious metals trading, money, financing ( to list just several of all kinds of investments ), are way too important. Different matters seek an accurate financial advice first, with a plan.
Super funds
Especially precise prices-versus-sizes of gold can have a crucial/pivotal role in investments. If there is an exact known measure in kt – K – carats (purity of gold) for gold amount, the rule is that the carat (purity of gold) number gets converted into g – grams or any other unit of gold absolutely exactly. It’s like an insurance for a trader or investor who is buying. And a saving calculator for having a peace of mind by knowing more about the quantity of e.g. how much industrial commodities is being bought well before it is payed for. It is also a part of savings to my superannuation funds. “Super funds” as we call them in this country.
Colour
Throughout history, gold has treasured for its natural beauty and radiance. For this reason, many cultures have imagined gold to represent the sun.
Yellow gold jewellery is still the most popular colour, but today gold is available in a diverse palette. The process of alloying—mixing other metals with pure 24 carat gold—gives malleable gold more durability, but can also used to change its colour.
White gold created through alloying pure gold with white metals such as palladium or silver. In addition it usually plated with rhodium to create a harder surface with a brighter shine. White gold has become the overwhelming choice for wedding bands in the US.
The inclusion of copper results in the soft pink complexion of rose gold while the more unusual colours such as blue and purple can obtained from the addition of patinas or oxides on the alloy surface. Black gold for example derives its colour from cobalt oxide.
Fineness
Fineness is another way of expressing the precious metal content of gold jewellery, and represents the purity in parts per thousand. When stamped on jewellery, usually this stated without the decimal point.
This chart shows some examples of the composition of various caratages of gold.
The alloying metal compositions above are typical of those used by the jewellery industry to arrive at the colour/caratage combinations shown, but these are not the only ways to arrive at these combinations.

White gold compositions listed here are nickel free. Nickel-containing white gold alloys form a small/very small percentage of white gold alloys and generally contain other base metals such as copper and zinc.
