What Is an Ounce?
An ounce (oz) is a unit of weight in the imperial system, commonly used in the United States and sometimes referenced in Canada.

What Is a Gram?
A gram (g) is a unit of mass in the metric system, which is officially used in Canada and most countries worldwide.
Grams are commonly used for measuring ingredients in cooking, food packaging, fitness, scientific purposes, and professional kitchens.
