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.
It is commonly used for measuring ingredients in cooking, food packaging, fitness, and scientific purposes.
One gram equals one-thousandth of a kilogram, making it ideal for precise weight measurements. Grams are used on nutrition labels, medical scales, laboratory equipment, and in professional kitchens for accuracy.
What Is an Ounce?
An ounce (oz) is a unit of weight in the imperial system, widely used in the United States and sometimes referenced in Canada.
It is commonly used in recipes, fitness measurements, and international shipping.
1 ounce equals approximately 28.3495 grams. While Canada primarily uses metric units, ounces are still seen in imported recipes, gym equipment, and cross-border shopping.

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 grams and kilograms
- Standard in science, healthcare, and food labeling
Imperial System:
- Uses ounces, pounds, and tons
- More common in the United States
- Less standardized globally
Because of this, Canadians often need to convert between these systems in cooking, fitness, and everyday life.
