Gold jewelry isn’t as easy to weigh in grams compared to coins or bars. However, you can use a digital jewelry scale set to grams and today’s gold price to estimate the value of your gold.

The troy ounce originated in Troyes, France during the 16th century as an approved unit of measurement for precious metals and stones. This measurement system is still used by dealers and buyers worldwide.

Troy ounce

In the world of precious metals, troy ounces are the standard unit used for measuring weight. It is highly unlikely that you will encounter any gold bullion products or coins that are not weighed in troy ounces. For those of you not familiar with the troy weight system, a troy ounce is heavier than a standard ounce (avoirdupois) – approximately 10% heavier.

For that reason, anyone who is purchasing or selling Precious Metals should become very familiar with the troy weight system. Although the origins of this measurement system are unknown, it is believed to have been developed in Troyes, a trading market in France, where merchants from around the world gathered to buy and sell goods. The system was later adopted by the UK and the United States, who both use it today to measure the price of gold and other precious metals. Regardless of the country, the system uses the same weight standards that we are all familiar with from everyday shopping.


When trading gold, it is important to understand the different types of measurement units. Depending on the type of gold you are purchasing or selling, it may be measured in grams, troy ounces, or karats. For example, a troy ounce of gold is equal to 31 grams. Regardless of the measuring unit you choose, it is important to be consistent when comparing your purchases or sales.

The term “gram” is derived from the Latin gramma, meaning small weight. One gram is roughly equivalent to the weight of a paper clip or pen cap. This makes it easy to visualize and compare the weight of gold items.

Most bullion bars and coins are marked with their weight in both ounces and grams. This makes it easier for investors to calculate the amount of gold they have. The gram system is also more accurate than the troy ounce, so it is the preferred unit of measurement for many investors.


A grain is a unit of measurement for precious metals. It is used to measure the mass of gold and silver. It also measures the density of the material. One gram of gold is equal to 0.065 grains. One troy ounce is equal to 480 grains.

Many new bullion investors buy gold in grains because it’s an affordable way to start investing in the precious metal. This small measurement is also more practical than buying large bars and selling them in bulk. One gram of gold is easier to transport and sell than 400 troy ounces of the metal.

While troy ounces are the standard in the world of gold, some countries use different units of measurement. For example, Southeast Asia uses tola, China uses tael, and Thailand uses baht. It is important to know the difference between these measurements so you can compare prices and sizes. You can find this information online or from local coin and pawn shops.


A gold pennyweight (abbreviated dwt) is equal to 24 grains and 1/20th of a troy ounce. It is a descendant of the old English Troy weight measurement system, which also included tower weights, ounces, and grains. In the Middle Ages, an English penny weighed about 32 tower grains. After 1527, troy weights replaced tower weights.

While gram gold prices are the most common way to weigh and value precious metals, some buyers still use the old pennyweight measurement. This can be confusing for sellers, since they may think that their gold is worth more in pennies than grams.

It is important to understand how much your metal lot weighs in pennyweights and grams before selling it. This will help you determine the best price for your precious metals and avoid being taken advantage of by dishonest gold buyers. You should always sell your scrap gold to a reputable company that provides pricing information in both gram and pennyweights.
