What is the formula for converting Fahrenheit to Celsius?

To convert a temperature from Fahrenheit to Celsius, the formula C = (F - 32) * 5/9 is used. This formula is derived from the relationship between the two temperature scales and is standard in conversion practices.

In this formula, the first step is to subtract 32 from the Fahrenheit temperature (F). This adjustment accounts for the different zero points of the two scales. In Fahrenheit, water freezes at 32 degrees, while in Celsius, it freezes at 0 degrees. After adjusting for this difference, the result is then multiplied by 5/9. This scaling factor reflects the rate at which the intervals in Fahrenheit convert to Celsius. Specifically, a change of 1 degree in Fahrenheit corresponds to a change of 5/9 degrees in Celsius.

The other options propose different calculations that do not correctly align with the established conversion methodology between Fahrenheit and Celsius. Therefore, using the formula C = (F - 32) * 5/9 yields an accurate Celsius temperature based on the given Fahrenheit measurement.
