Question: What Temperature Does Fahrenheit Equal Celsius?

There is one point on the Fahrenheit and Celsius scales where the temperatures in degrees are equal. Here is the answer to what temperature Fahrenheit equals Celsius and an explanation of how to solve the problem.

Answer: Rather than converting one temperature to another, you set them equal to each other. You can solve this problem by solving for x:

x = 5/9 * (x - 32)

x = (5/9)x - 17.778

1x - (5/9)x = -17.778

0.444x = -17.778

x = -40 degrees Celsius or Fahrenheit
