# Convert gram to ounce

## What is a gram?

During ancient times, our predecessors were constantly looking for some standards for mass determination. It was easy and practical to evaluate mass in comparison with some grains or seeds of plants. Then, they were replaced by coins made of different metals.

However, not all these options were precise and they also differed in counties and regions. These were the reasons for the development of a gram as a unified option in the 18th century. According to the definition, 1 g was equal to the mass of 1 cm3 of distilled water. The measurement must be made at 4 °C temperature and one atmosphere pressure.

Later, grams were replaced by kilograms as a new more convenient standard. For them, a special object was created for comparison and determination of mass. Still, grams were also left for measurements and nowadays 1 gm is considered as 1/1000 of a kg.

## What is a ounces?

In ancient Rome, an ounce was utilized for mass determination and was approximately equal to 27.3 grams. The word itself meant one-twelfth and corresponded to one-twelfth of other units common for trade and the ancient monetary system.

One modern ounce or oz is determined as nearly 28.3 grams. This option is not a standard as an international system works with kilograms and their fractions. However, many English-speaking countries stick to it due to the tradition and utilize it for mass, weight and volume determination as 1/16 of a pound.

Thus, one can often encounter ounces in the USA and Great Britain. It is utilized for weighing packaged foods and postal items, for the determination of the density of cloth and paper, etc. Moreover, there is a troy ounce, equal to 31.1 grams, that measures the weight of precious metals. The ounce-force for force determination also exists and the fluid one allows working with volumes.
