How to Convert Celsius to Fahrenheit (°C to °F)

You want to convert from Celsius to Fahrenheit. Although you’ll offer your response in degrees Celsius to degrees Fahrenheit, you should be aware that there are two different temperature scales: Celsius and Fahrenheit. Although it won’t affect your final response, it’s still a good idea to be aware of this if you ever need to spell out the names. The conversion is relatively simple.

Celsius to Fahrenheit Conversion Formula

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

°F = (°C × 9/5) + 32

It’s just as easy to convert Fahrenheit to Celsius.

°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

Table of °C and °F Temperature Conversions

It would be helpful to check up on significant temperatures, such as core body temperature, water freezing and boiling points, etc. Here are a few typical significant temperatures in both Fahrenheit and Celsius (the US temperature scale):

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

The exact temperatures are shown in bold. The closest degree has been used to round other temperatures that are close.

Key Points

Two significant temperature scales, Celsius and Fahrenheit, are sometimes misspelled as Celcius and Fahrenheit.

  • The formula to convert Fahrenheit temperature to Celsius is °C = (°F − 32) x 5/9
  • The formula to convert a Celsius temperature to Fahrenheit is °F = (°C 9/5) + 32.
  • At -40°, the two temperature scales are equivalent.
