Ounces to Stones

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.

Stone

A stone (st) is a unit of weight used primarily in the United Kingdom and Ireland, especially for measuring body weight. One stone equals 14 pounds, or roughly 6.35 kilograms. Because it provides a convenient number for typical human weights, stones remain popular in health, sports, and everyday conversations.

Although stones are not used in the metric system or the United States, conversions are often needed for travel, fitness tracking apps, or international communication. A converter helps provide a quick translation to pounds or kilograms.
