What Is an Ounce?

An ounce (oz) is a unit of volume in the imperial system, widely used in the United States and sometimes referenced in Canada.

Fluid ounces are commonly used in recipes, beverages, and international product labeling.

1 U.S. fluid ounce equals approximately 29.5735 milliliters. While Canada primarily uses metric units, ounces are frequently seen on imported beverages, international recipes, and some restaurant menus.

What Is a Milliliter?

A milliliter (mL) is a unit of volume in the metric system, which is officially used in Canada and most countries worldwide.

Milliliters are commonly used to measure liquids such as water, milk, juice, oil, and other beverages.

One milliliter is one-thousandth of a liter, making it ideal for precise measurements. Milliliters are widely used in food packaging, nutrition labels, medical applications, and professional kitchens.

What’s the Difference Between Metric and Imperial Systems?

The metric system and the imperial system are two distinct measurement standards.

Metric System (used in Canada):

  • Based on units of 10 (easy to convert)
  • Uses milliliters and liters
  • Standard in science, healthcare, food labeling, and education

Imperial System:

  • Uses ounces, cups, teaspoons, and tablespoons
  • More common in the United States and some international recipes
  • Less standardized globally

Because of this, Canadians often need to convert between these systems for cooking, beverages, and international travel.

Canada officially uses the metric system, but in everyday life, Canadians use a mix of both.

Ounces:

  • Imported beverages and products 
  • Recipes from the U.S. 
  • Restaurant menus and drink sizes 
  • Informal or international cooking use

Milliliters:

  • Beverage containers (milk, juice, soda) 
  • Cooking measurements on packaging 
  • Medical and official measurements 
  • School and government use
