Temperatures in Canada: Convert Fahrenheit to Celsius

Along with many countries around the world outside of the United States, Canada uses the metric system to measure the weather in degrees Celsius (C) instead of Fahrenheit (F). As a result, you'll want to familiarize yourself with common temperatures you might encounter before you travel to Canada.

Whether you're trying to convert 15 Celsius to 60 Fahrenheit to see if you'll need a light jacket for a chilly afternoon or 30 Celsius to 85 Fahrenheit to know it's going to be a hot day, knowing how to convert temperatures between these systems will help you know what to expect.

In addition to temperatures, the Canadian metric system also differs from the Imperial system of the United States when measuring weight in grams, kilograms, ounces, and pounds; distances in meters and kilometers; speed in kilometers per hour; and volume in liters and milliliters.

Conversion Formula for Celsius to Fahrenheit

In order to convert temperatures in degrees Celcius to degrees Fahrenheit, you can either double the temperature in Celsius and add 30 to get a close estimate or use the following formula to get an exact measurement:

  • (C x 1.8) + 32 = F
  • Example: 20 C = (20 x 1.8) + 32 = 68 F

Visitors should note that "wind chill" is a major factor that affects the temperature in cold climates like Canada, and in winter, temperatures are often presented with the wind chill factor. Thus, a weather report on a chilly January morning may report the temperature as -20 C (-4 F), the wind chill factor will make the "real feel" temperature will be closer to -30 C (-22 F).

If you're not mathematically inclined, a great way to understand the normal range of temperatures in Canada is to remember this short poem: "Zero is freezing; 10 is not. 20 is warm, and 30 is hot."

Common Temperatures in Celsius and Fahrenheit

Just like Americans have a general understanding that 32 F is the temperature at which water freezes, 50 F is the appropriate weather for a fleece jacket, and everything over 85 F is considered hot weather, Canadians also share similar reference points for temperatures in Celcius.

Measurement  Celsius Fahrenheit
Boiling point   100 C      212 F
Sweaty, hot weather Over 30 C   Over 85 F
T-shirt and shorts weather     24 C        75 F
Average room temperature     21 C        70 F
Long-sleeve shirt and pants weather     15 C       60 F
Fleece jacket weather     10 C       50 F
Freezing       0 C       32 F
Frigidly cold and potentially dangerous outdoors    - 29 C     - 20 F
