Gram to Ounce Converter

A gram (g) is a unit of mass in the metric system equal to one-thousandth of a kilogram (0.001 kg). It is commonly used for measuring small quantities and lightweight objects.

The gram was originally defined in 1795 as the mass of one cubic centimeter of water at 4°C. The name comes from the Greek word 'gramma' meaning 'small weight'. It was part of the original metric system and has remained a fundamental unit for small mass measurements.

Grams are extensively used for measuring food ingredients in cooking and baking, medication dosages, jewelry, precious metals, and small consumer products. They're standard in nutrition labels, pharmaceutical prescriptions, and scientific measurements for lightweight materials.

An ounce (oz) is a unit of mass in the imperial and US customary systems, equal to 1/16 of a pound or approximately 28.35 grams. The avoirdupois ounce is the most common variant.

The ounce derives from the Roman 'uncia' meaning 'twelfth part', originally 1/12 of a Roman pound. The avoirdupois ounce evolved from medieval English trade weights and was standardized as part of the imperial system. It was internationally defined as exactly 28.349523125 grams in 1959.

Ounces are commonly used in the United States for measuring food portions, postal weights, precious metals, and small consumer products. They're standard for nutrition labels, recipe measurements, jewelry, and in retail for products sold by weight in imperial system countries.
