How Many Grams in an Ounce of Gold?

When it comes to comparing prices, sizes, or calculating the premium, it is important for investors to understand exactly how much gold they have. A common cause of confusion in this regard takes place with gold coins, which are most commonly minted and quoted in ounces. How many grams are in an ounce of gold? 31.1 grams is the most common answer, and one simple enough for most purposes. Below we discuss this in more detail however, for those looking for further understanding.

How many grams does an ounce of gold contain?

There are 31.1034768 grams in an ounce of gold to be more precise than above. This can be confusing for those of us who are used to the standard ounce (or kitchen ounce) which weighs 28.35g. That is because there are in fact two types of ounce - the ‘troy’ ounce and the ‘avoirdupois’ ounce.

The troy ounce is the one most commonly used in the world of precious metals, and is the default unit of weight when measuring gold, silver, and platinum. It is often used in reference to the gold price which is usually quoted in pounds, dollars, or euros per troy ounce.

The troy ounce is an imperial unit of measurement whose use dates back hundreds of years and since the 16th Century has been the official unit for precious metals. Many gold and silver bullion coins contain or weigh one troy ounce of gold, including the Britannia, Canadian Maple Leaf, and Krugerrand.

If you know the weight of your gold in grams and wish to find out how many troy ounces it weighs you need to multiply its weight by 0.03215.
