There isn't a simple one-to-one conversion between Celsius and Fahrenheit. They use different starting points and scales.

Here's why:

* Celsius: Uses the freezing point of water as 0°C and the boiling point as 100°C.

* fahrenheit: Uses the freezing point of water as 32°F and the boiling point as 212°F.

To convert between Celsius and Fahrenheit, you need to use the following formulas:

* Celsius to Fahrenheit: ° F =(° C × 9/5) + 32

* Fahrenheit to Celsius: ° C =(° F - 32) × 5/9

Therefore, there is no single Celsius value that is equal to 1 Fahrenheit.
