How much does a gold bar weigh?

Weight of a gold bar can vary depending on its size and the standard used. One of the most common standards for gold bullion is the London "good delivery" standard, which weighs approximately 400 troy ounces (about 12.4 kilograms).

According to the Russian GOST, ingots weigh from 11,000g to 13,300g. There are also smaller bars weighing from 1g to 1,000g. Usually the rotation of ingots in a jar by weight is as follows

• 1 g.
• 2 g.
• 2.5 g.
• 5 g.
• 10 gr.
• 20 gr.
• 31.1 g.
• 50 gr.
• 100 gr.
• 250 gr.
• 500 gr.
• 1000 gr.

In addition to the London "good delivery" standard and GOST, there are other gold bar standards that vary in weight and size. Here are just a few of them:

1. Kilogram ingot (1000 grams): This standard is widely used throughout the world, especially in Asia and Europe. The weight is 1000 grams or 32.15 troy ounces.
2. The Troy ounce (31.1035 grams): The troy ounce is the standard measure of weight for precious metals such as gold, silver and platinum. Gold bars of this standard weigh exactly one troy ounce (31.1035 grams).
3. 10-ounce bullion (311.0348 grams): This standard includes gold bars weighing 10 troy ounces (about 311.0348 grams).
4. 5-ounce bullion (155.5174 grams): These bars weigh 5 troy ounces (about 155.5174 grams).
5. Combi bars: Combi bars are a set of small ingots or bars that can be divided into individual units. They are usually available in different sizes and weights, including 50 grams, 20 grams, 10 grams, etc.

There are also other national and regional gold bullion standards.

The photo shows a bar of Thai gold equal to the weight of 1 baht. This is one of the regional standards. In Thailand, gold is measured in baht, with a more accurate scale, the weight would be 15.244 grams.

Below is a list of a few more regional standards:

1. Swiss bullion: Swiss gold bullion is widely known for its high accuracy and quality. They usually range in weight from 1 gram to 1 kilogram. In Switzerland, the pound bullion is the most popular.
2. Australian bullion: The Perth Mint produces gold bullion in a variety of sizes and weights, ranging from 1 gram to 1 kilo. The most common are ingots of 1, 10, 20, 50, 100 grams and 1, 10 and 32.15 troy ounces.
3. Chinese bullion: In China, gold bullion weighing from 10 grams to 1 kilogram is preferred. These bars are usually produced by the Chinese National Mint and have distinctive patterns and symbols on the surface.
4. Turkish bullion: In Turkey, gold bars called "Gold Reserve" (Altin Rezerv) are common. They have a standard weight of 1, 2.5, 5, 10, 20, 50 and 100 grams.
5. Indian bullion: In India, gold bars often weigh 10 grams, 20 grams, 50 grams, 100 grams and 1 kilo. Gold coins depicting deities and symbols such as Ganesha and Lakshmi are also popular in India.

The conclusion is that the weight of a gold bar is far from a standard/uniform unit.
