Definitions of Ounces and Grams

Before we get to the actual conversions, let’s start with some definitions.

What Is an Ounce

An ounce (abbreviated oz) is a unit of measurement equal to 1/16th of a pound, or approximately 28 grams. An ounce is often used in the United States, the United Kingdom, and other countries that use the Imperial measurement system to measure weight and mass, with one ounce equal to approximately 28.35 grams. In the imperial system, an ounce is equal to approximately 1/12th of a pound.

There are also fluid ounces which measure volume, but given that grams refer to mass we will stick to the dry weight measurement of ounce for this article. If you are asked to measure dry ingredients, such as flour, you are probably being asked to measure weight and therefore traditional ounces.

What Is a Gram

A gram is a metric unit of mass and is equal to 1/1000 of a kilogram. Kilo in Greek means “thousand” so a kilogram is 1000 grams.

Many international recipes use grams in recipes to specify how many ingredients to include. European measuring cups also usually use grams (as opposed to ounces and cups on American measuring cups).
