Summary

What’s Inside

Gold is one of the most sought-after precious metals for investment. The higher the demand, the greater the chances of adulteration in its composition. Through gold weight measurements and purity identification, you can find solace in the worth of your investment.

The weight of the precious metal is usually calculated in units termed troy ounces and grams. Similarly, the purity of gold is measured in karats or its fineness. In this article, you will understand different ways of calculating gold measurements.

If you've been considering gold as an investment, go through this guide to learn how to assess its weight and purity.

Measuring the Weight of Gold

Gold is measured in grams, troy ounces, and tola.

  • Ounces

A standard ounce is typically used to weigh gold bullion, while a troy ounce measures the precious metal in the gold market. Troy ounces are used to assess gold bullion weight. If you want to measure in troy ounces, you don't need to equate it with regular ounce weightage. The standard ounce is 28.34 grams, while a troy ounce is 31.10 grams.

The smaller gold merchants use 100-Troy-ounce bars. More prominent merchants deal in 400-Troy-ounce bars, generally.

  • Tola

Tola is also a method of gold measurement prevalent in Asia. It is equivalent to 11.66 grams and 3/8th of a troy ounce. This measurement indicator is preferred for jewellery and, in some cases, gold bars.

  • Grams

Gold measurement unit for weight is grams, too. One-fifth of a gram is considered for each carat of gold. Therefore, to measure the total weight of gold in grams, you must multiply 0.2 grams by a karat. So, the weight of 10K gold equals two grams.

You can also consider the weight of the gold in milligrams. One karat equals 200 milligrams.

Measuring the Purity of Gold

In India, the gold measurement unit for purity is karats or carat (K). If gold is pure, its caratage measure will be 24. Each karat holds 1/24th proportion of the whole gold unit. That's to say — it carries 4.1667 per cent of the total purity weightage.

Since gold is highly malleable, it is mixed with other metals to convert it into jewellery and other gold objects. The common caratage of these objects lies in the range of 10K to 22K.

You can also check the purity of gold through the BIS identification for gold hallmarks.

The Final Assessment

To determine the purity of the gold, you need to weigh the entire gold object using a sensitive scale. After this, Multiply the weight of the object by the purity percentage. To get the correct gold measurement, ensure the weight is in grams.

For example, 18K gold jewellery is 18 parts gold and eight parts alloy metal. That means the jewellery carries 75% pure gold and 25% mixed metal.

So, your 8-gram gold object equates carries 75% purity.

It's essential to know the worth of the purchased object by understanding the product's current market value. You can get all the information on the Fi app for higher ROI.
