Fahrenheit and Celsius are two temperature scales. With a simple equation, it is easy to convert a certain number of degrees from Fahrenheit to Celsius, or vice versa. This article explains how to convert between the two scales.

Difficulty: Easy
Instructions

Things You'll Need:

  • pen/pencil
  • paper
  • calculator
  1. Step 1

    Start by writing the equation F=1.8C+32. F refers to the number of Fahrenheit degrees, and C refers to the number of Celsius degrees.

  2. Step 2

    Fill in the value that you are given. It will be either Fahrenheit or Celsius.

  3. Step 3

    Solve for the missing variable.

  4. Step 4

    As an example, let us convert 50 degrees Fahrenheit to Celsius. We would plug in 50 for F to get 50=1.8C+32. Now subtract 32 from both sides to get 18=1.8C. Finally, divide both sides by 1.8. C=10, so the corresponding Celsius temperature is 10 degrees Celsius.

  5. Step 5

    As another example, we will convert 5 degrees Celsius to Fahrenheit. Plug in 5 for C to get F=1.8(5)+32. Simplify this now, so F=41 degrees, so the corresponding Fahrenheit temperature is 41 degrees.
