How to Convert Between the Fahrenheit and Celsius Temperature Scales

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

3. Solve for the missing variable.

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. 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.
