Grams to Ounces

Gram

A gram (g) is a metric unit equal to one-thousandth of a kilogram. It is ideal for measuring lighter items such as spices, medication, small hardware, and jewelry. Because it fits well for everyday small quantities, grams are widely used in cooking, product packaging, and laboratory work.

As part of the metric system, converting grams to kilograms or milligrams is quick and intuitive. But switching between grams and US customary units often requires exact conversion factors, where a converter becomes essential.

Ounce

An ounce (oz) is a small US customary unit of weight equal to 1/16 of a pound, or about 28.35 grams. It is commonly used in cooking, portion sizes, mail weighing, and food packaging. Ounces provide a practical scale for items too small for pounds but too large for grams alone.

Although the same word, ounce, also refers to a liquid measurement (fluid ounce), the two units are completely different. This converter focuses on ounces used for weight.
