When you’re baking or cooking, you’ll need to follow the recipe and ensure that you’re using the appropriate amount of each ingredient to arrive at the final product. Too much of one ingredient and too little of another can completely throw off your recipe. 

To make sure you’re using the right amounts of each ingredient, you’ll usually need to measure its weight.

In Canada, you can use either grams or ounces to weigh solid or semi-solid food products. But what if a recipe lists ingredients in one unit of measurement, but you need to convert it to the other? 

Read on to find out how to convert grams to ounces, and vice versa.

What Is A Gram?

The gram is a unit of mass in the metric system and is symbolized as ‘g’. It is a commonly used unit of measurement for non-liquid ingredients in cooking recipes and grocery items. Food product label standards typically require the contents to be stated per 100 grams.

The weight of food products is typically labelled in grams, particularly those in quantities far less than a kilogram. 

When Are Grams Used? 

While the gram can be used in various scientific contexts, it’s more often used to measure ingredients when cooking or for grocery items. For smaller food items, you’ll notice their weight quoted in grams on their labels. 

What Is an Ounce?

The ounce is a unit of mass in the imperial system of measurement and is symbolized as ‘oz’. The common ounce is precisely 28.349523125 grams and is equal to 1/16th of a pound.

When Are Ounces Used?

The ounce is commonly used in the US to measure packaged food products and portions, and postal items, though it may also be used in other settings. While predominantly used in the US, the ounce is also sometimes used in other countries with ties to British history. However, the UK no longer uses the ounce officially due to metrication.

Does Canada Use The Metric Or Imperial System?

Canada has officially used the metric system of measurement since the 1970s, so grams would be the official unit of measurement. However, both metric and imperial units are used in Canada, so it’s not uncommon to see ounces used to measure the weight of food products. 

More specifically, the type of measurement system used depends on what is being measured. For example, the weight of food products can be measured in either imperial or metric units, while the weight of a person is usually measured in imperial units (ie. pounds).
