How to Measure Gold Weight? Know Gold Purity
It is universally accepted that gold is an everlasting and valuable asset. This reality raises the challenge of how to measure gold weight. Gold purity and weight are measured by using many different units around the world.
The density of gold can be effectively determined by dividing the mass of the gold sheet by its volume. Whereas, the purity of gold can be measure by karats. Divide the total volume of gold in 24 equal parts and check out how many parts are gold in 24 parts. That will be the exact karat for understudied gold.
- Density = Mass of Gold/Volume
- Gold Mass = Density * Volume
How to Measure Gold Weight in Different Units:
There are different units used to measure gold. Gram is the standard unit. However many other matrices system are introduced for measuring gold. whereas, if you need to check the purity of the gold, gold carat system is used. Some of the most commonly used units by weight are given below.

- One Troy ounce = 31.1 Grams
- One ounce = 28.35 grams
How Much Gold in One Pennyweight?

It is typically used for measuring the weight of very small gold pieces while creating jewelry. Let me tell you which gold weight unit is used by dentists or in dental labs. They use gold in pennyweights for dental applications.

- Pennyweights = 1.555 grams
How Much Gold Weighs In Grams?
The most common unit for measuring gold is the gram. One carat contains One-fifth gram of gold, which equals 0.2 grams. A carat can also be measured by multiplying a carat by 0.2 grams. A kilogram is also the common unit to calculate the gold price. One kilogram contains 1000 grams.
There is point to understand. Carat is the gold mass measuring unit whereas, Karat is the quality measuring unit for gold.
- One Carat = ⅕ Gram Gold = 0.2 grams
- 18 carats = 18 * 0.2 grams = 3.6 grams
- 1 gram = 1000 milligrams
- 200 milligrams = 1 karat.
- 1 kilogram = 1000 grams
Measuring Gold by Purity:
The measurement of gold is of two types, by weight or by quality. For weight measurement different units are used like gram, ounce, vori, tola and many more. However, the quality of gold is checked by one unit, carats. In this system we assigned different carat number to the gold depending upon the quality of it.
Different Carats used:
It is necessary to know how pure your gold is. So, the Carat system is used to determine gold’s purity. It is represented by the letter C. The highest carat of gold is 24 carats. A higher carat value means that our gold contains more pure gold. Let’s have a look at some of the gold karats.
24C refers to a purer form of gold. Which is 99.999 percent pure and means that 24 out of 24 parts are gold and contain no impurity (approximately). It is very soft and breaks or mold easily. This type of gold is not utilized in making jewelry because of its softness.
22C is a mixture of gold that is 91.6% pure, and the rest of the part contains impurities like copper, palladium, silver, etc. However, keep in mind that this kind of gold is appropriate for making jewelry. It is not recommended for jewelry that is highly set with diamonds or other hard gemstones.
When 87.5% pure gold is mixed with other metals, then 21C gold is formed. 3 parts of other metals are blended with 21 parts of gold. 21C gold is preferred for simple gold jewelry because 22C gold is too soft for pieces with stones.
A mixture of other metals and 75.0 percent pure gold is called 18 C. It is less expensive than 24 C, 22 C, and 21 C. So, not suitable for sensitive skin and can cause skin allergies. 18 C gold is less expensive than other higher carats.
