In Canada, the United Kingdom, and several other European countries, temperature is measured in degrees Celsius (°C). In the United States, Belize, the Bahamas, the Cayman Islands, and Palau, temperature is measured in degrees Fahrenheit (°F).[1] Luckily, it’s easy to convert between the two whenever you may need to. Simply plug the known temperature into the relevant equation to convert.

Converting Celsius to Fahrenheit

  1. 1
    Note that the equation is °F = (°C x 1.8) + 32. You may also use the equation °F = °C x 9 ÷ 5 + 32, which will produce the same answer since 9 ÷ 5 = 1.8.[2] You can plug any Celsius temperature into either equation to convert it to Fahrenheit.
  2. 2
    Multiply the Celsius temperature by 1.8. First, take the Celsius temperature and multiply it by 1.8.[3]
    • For instance, if the Celsius temperature is 20, multiply 20 by 1.8, which equals 36.
    • Alternatively, multiply the temperature (20) by 9, which equals 180, then divide 180 by 5, which equals 36.

    Add 32 to the product. After multiplying the temperature by 1.8 (or by 9, then dividing by 5), add 32 to the answer.[4]
    • In this case, add 32 to 36 which equals 68. So, 20°C is equal to 68°F.

Method 2 of 2:

Changing Fahrenheit to Celsius

  1. 1
    Recognize that the equation is °C = (°F - 32) ÷ 1.8. You could also use the equation °C = (°F - 32) x 5 ÷ 9 to get the same result.[5] Simply plug in any Fahrenheit temperature and do the math to convert °F to °C.[6]
  2. 2
    Subtract 32 from the Fahrenheit temperature. The first step is to take away 32 from the temperature in Fahrenheit.[7]
    • For example, if the Fahrenheit temperature is 90, subtract 32 from 90 to get 58.
  3. 3
    Divide the answer by 1.8. After subtracting 32 from the temperature, the next step is to divide the answer by 1.8.[8]
    • For example, divide 58 by 1.8 to equal 32.22. So, 90°F is equal to 32.22°C.
    • Or, you could multiply 58 by 5, which equals 290, then divide 290 by 9, which equals 32.22. Either way, 90°F is equal to 32.22°C.

Article SummaryX

To convert Celsius to Fahrenheit, start by multiplying the Celsius temperature by 1.8. Then, add 32 to the product to get the degrees in Fahrenheit. For example, if you were trying to convert 20 degrees Celsius to Fahrenheit, first you'd multiply 20 by 1.8 to get 36. Then, you'd add 32 to 36 and get 68. Therefore, 20 degrees Celsius is equal to 68 degrees Fahrenheit. To learn how to convert Fahrenheit to Celsius, scroll down!
