You're looking to convert Celcius to Fahrenheit. While you'll give your answer in °C to °F, you should know the temperature scales are Celsius and Fahrenheit. It doesn't matter for your final answer, but if you're ever expected to spell out the names, it's good to know. The conversion is really easy:

Celsius to Fahrenheit Conversion Formula

Multiply the °C temperature by 1.8. Add 32 to this number. This the answer in °F.

 °F = (°C × 9/5) + 32

It's just as easy to convert Fahrenheit to Celcius;

°C = (°F − 32) x 5/9

Example °C to °F Conversion

For example, to convert 26°C to °F (the temperature of a warm day):

 °F = (°C × 9/5) + 32

 °F = (26 × 9/5) + 32

°F = (46.8) + 32

°F = 78.8° F

Sometimes it's good to just look up important temperatures, like body temperature, the freezing point and boiling point of water, etc. Here are some common important temperatures, in both Celsius (the metric scale) and Fahrenheit (the US temperature scale):

°C °F Description
-40 -40 This is where Celsius equals Fahrenheit. It's the temperature of an extremely cold day.
−18 0 An average cold winter day.
0 32 The freezing point of water.
10 50 A cool day.
21 70 A typical room temperature.
30 86 A hot day.
37 98.6 Body temperature.
40 104 Bath water temperature.
100 212 Boiling point of water at sea level.
180 356 Baking temperature in an oven.

Bold temperatures are exact values. Other temperatures are close but rounded to the nearest degree.

Key Points

  • Celsius and Fahrenheit are two important temperature scales that are commonly misspelled as Celcius and Farenheit.
  • The formula to find a Celsius temperature from Fahrenheit is:  °F = (°C × 9/5) + 32
  • The formula to find a Fahrenheit temperature from Celsius is:  °F = (°C × 9/5) + 32
  • The two temperature scales are equal at -40°.
