Does Canada use Celsius? Both yes and no. Officially, Canada uses the Degrees Celsius, but some parts and some (older) people can still use Fahrenheit. Still, over 40 years ago, on April 1, 1975, Canada officially switched to Celsius, made it much easier for scientists and industries to implement high-precision scales. 

Although the temperature scale that is used really makes no difference when it comes to the cold weather, switching to Celsius brought Canada on track with the rest of the world. It made measurements in the Imperialistic system obsolete, and the newly implemented Metric system made manufacturing and designing of products much easier. 

Does Canada Use Fahrenheit or Celsius?

Regarding the temperature readings, as the weather is a common chit-chat topic, this probably brought about a huge difference in the daily lives of then-contemporary Canadians. When the switch to Celsius was implemented, the weather forecast suddenly switched to Celsius. This was a big difference for many, and it took a while to accommodate.

When did Canada Start Using The Unit Celsius?

On April 1st, 1975, Canada officially switched to Celsius. This meant a big shift in the way Canadians observed weather, did their measurements (especially in sciences), and the way that products were labelled. However, many domestic appliance manufacturers, to save and increase efficiency, started putting both scales on their products: it is still common to find oven temperatures in both scales on older models, while the digital models let you choose the scale you want to use, much like you can do wit any weather app. 

Laws About Temperature Measurement in Canada

At the same time, all official institutions had to make a switch to Celsius. Although some used conversion charts and math formulas, some found it difficult to understand the actual temperatures: Imagine working at Environment Canada back in the day and having to convert hundreds of temperature readings every day till you got used to the Celsius scale. 

Practical Everyday Usage in Canada

However, when it came to an average Canadian, the difference was there, but it was simply not big enough to allow for a change in the way the weather was perceived: chilly weather was just as chilly, although the temperature reading said 10°C, and not 50°F like before. At the same time, hot weather was equally as hot, but the old thermometer reading of 100°F+ was gone. 

What Is The Impact of Using Celsius in Canadian Industries

However, it was the industries that took the blow. Suddenly converting temperatures using charts and formulas for the weather forecast is one thing, but having to convert them and get used to a new way to model temperatures was at times even dangerous in some industries. Look at the pharmaceutical industry and how sensitive all the ingredients are to temperature instabilities and changes. 

What to Expect When You Arrive In Canada?

This was one of the reasons that many thermometers and thermostats back in the day had a dual reading – one for °C and one for °F, and they can still be found in many older homes and buildings, especially those that haven’t been refurbished in a while. 

Still, knowing the right temperature is very important, whatever the scale you are using. For example, driving across Canada in winter can even be dangerous if you set on a long road trip and misread the weather forecast. The old reading of 32°F may not seem too low, but the Celsius equivalent of 0°C means that there may be ice on the road. For this reason, it is always advisable to double-check the temps and the official weather source – to stay safe on Canadian roads during winter weather conditions. 

Temperature Scale Used in Canadian Airports

The extreme weather is not the only way this could be dangerous. Imagine travelling from the USA to Canada and checking the airport website only to find that the reading shows 0°C. While some states that border Canada (only the USA) might cancel their trip, a simple conversion to the Fahrenheit scale would show a day that is fresh by Canadian standards, not cold at all. 

How to Prepare for Canadian Weather

So, is Canada a good place to live in? Yes, it is. Regardless of the temperature scale used, Canada is still very comfortable to live in. The snowy weather and Celsius-based weather reports can be somewhat confusing, but the country has so much to offer that this simply stumbling rock should not push away an average American.

Differences According To Region

There are differences in some regions, though, as some wanted to keep using the imperialistic scale. These parts may show some of the temperatures in the degree Celsius weather – while other temperatures may be using the Fahrenheit scale – such as the gas mark temperature. 

Places in Canada that Still Use Fahrenheit

If you asked an average Canadian what places use Fahrenheit, they would probably be confused. In reality, Fahrenheit is only used by people older than 55 or even 65 and only occasionally for safety reasons: HVAC controls and oven temperatures are often shown in both to avoid mistakes and injury. Imagine turning up a Celsius oven to 350°C, instead of 350°F – the result would be a burnt lunch and potentially burnt house. 

How to Convert Between Celsius and Fahrenheit

Still, if you travel to Canada from the USA, you must know how to convert between the two. Some of the measurements are easy to memorize: 

  • normal room temperature is 20°C
  • normal body temperature is 37°C
  • water freezes at 0°C
  • water boils at 100°C

Still, as this is not enough, here is a simple formula to convert the Celsius to Fahrenheit: 

°F = 9/5 x °C + 32°F
For Example:  °F = 9/5 x 20°C + 32°C °F = 68°F

Does Canada use Fahrenheit or Celsius for Baking Too?

Canada uses both Fahrenheit and Celsius when it comes to baking. The reasons are multiple: sometimes, the added scale means added safety. The other important reason is the vicinity of the US and its influence: recipes and baking temperatures are always expressed in °F. 

What Countries Use Celsius or Fahrenheit?

There are still several countries that use Fahrenheit. They include the USA, American Samoa, Cayman Islands, Guam, Liberia, Marshall Islands, Micronesia, Northern Marianas Islands, Palau, Puerto Rico and US Virgin Islands. The rest of the world uses Celsius or a mix of both.

Do Canadians Use Inches or cm?

Officially, Canada uses a full metric system – including temperatures and length. However, the vicinity of the US means that many Canadians know both. For this reason, they can use both inches and centimetres to express some common dimensions, such as their height. 


The switch to °C in Canada was a long process that started back in 1975. Today, Canada officially uses the metric system to express the temperature, but many older generations and those living close to the US or being exposed to a lot of US media can use both metric and imperialistic scales. In any case, both scales were kept where it made sense, as well as where it would increase safety, such as common home appliances.
