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. It is commonly used for measuring liquids such as water, milk, oil, juice, and other beverages.
One milliliter equals one-thousandth of a liter, making it ideal for precise measurements. Milliliters are used in professional kitchens, food packaging, nutrition labels, and scientific applications, providing accurate and consistent results.
What Is an Ounce?
An ounce (oz) is a unit of volume in the imperial system, widely used in the United States and occasionally referenced in Canada.
Fluid ounces measure liquid volumes and are often 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 commonly seen in imported recipes, beverage containers, and restaurant menus.

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.
Does Canada Use Milliliters or Ounces?
Canada officially uses the metric system, but in everyday life, Canadians use a mix of both.
Milliliters:
- Beverage containers (milk, juice, soda)
- Cooking measurements on packaging
- Medical and official measurements
- School and government use
Ounces:
- Imported beverages and products
- Recipes from the U.S.
- Restaurant menus and drink sizes
- Informal or international cooking use
