How do you convert Fahrenheit to Celsius?

The correct method for converting Fahrenheit to Celsius is through the formula C = (F - 32) × 5/9. This formula establishes a relationship between the two temperature scales.

In this conversion, the starting point involves taking the Fahrenheit value and subtracting 32, which serves to align the zero points of both scales since freezing (32°F) and boiling (212°F) points differ. The result is then multiplied by the fraction 5/9, which accounts for the different size of the degree units between Fahrenheit and Celsius. Specifically, a change of 1 degree Celsius is equivalent to a change of 1.8 degrees Fahrenheit, hence the factor of 5/9 simplifies this relationship for conversion.

Using the other formulas would yield incorrect results, as they either incorrectly adjust the scale or switch the operations necessary for accurate conversion between these two systems.
