G to Oz

As the symbol for a gram is g, and as the unit symbol for ounce is oz, the conversion is often abbreviated as g to oz.

Now, let’s look at the different kinds of ounces currently in use:

The ounce under consideration here is known as International avoirdupois ounce, used for the weight or mass of a product typically sold in US groceries and found in a cookbook.

It is defined as 28.349523125 g, and outside of retail used to measure bulk dry goods.

Thus, the information provided in this article is not about the fluid ounce, which is a unit of volume.

Unless stated differently, the information on this page does not apply to the International troy ounce either; that unit is only used to measure precious metals like gold for example.

The international troy ounce is exactly 31.1034768 grams, approximately ten percent more than the avoirdupois ounce.

In the next paragraph we show you how to change the units.

How to Convert Grams to Ounces?

To change g to oz divide the mass in grams by 28.349523125.

The grams to ounces formula is [oz] = [g] / 28.349523125.

Therefore, for instance, 10 g are equal to approximately 0.35 International avoirdupois ounces.

(To convert grams to troy ounces divide the mass in grams by 31.1034768.

The grams to troy ounces formula is [troy oz] = [g] / 31.1034768.

For example, 10 g gold or silver are more or less 0.32151 international troy ounces.

Remember, only use the troy ounces formula for gold, platinum, silver and palladium for example.)

Throughout our site, unless stated otherwise, we mean the avoirdupois ounce used to weigh dry foods, such as in the case of our calculator above.
