What is the formula to convert Fahrenheit to Celsius?

The correct formula to convert Fahrenheit to Celsius is expressed as ((F - 32) \times \frac{5}{9} = C). This equation outlines the steps necessary to transform a temperature measured in Fahrenheit (F) into its Celsius equivalent (C).

To break it down, the process starts by subtracting 32 from the Fahrenheit temperature. This adjustment accounts for the difference in the starting point of the two temperature scales. Next, the result is multiplied by (\frac{5}{9}), which reflects the conversion factor between the increments of temperature on the Fahrenheit scale compared to the Celsius scale. Each degree Celsius represents a larger increase in temperature compared to a degree Fahrenheit, thus necessitating this multiplication.

This formula is also consistent with the foundational principles of temperature conversion, ensuring that when you input a Fahrenheit temperature, you correctly calculate the corresponding Celsius value. Understanding this conversion is particularly important in medical and scientific contexts where precise temperature readings are crucial for diagnosis and treatment.

Other formulas provided in the options do not accurately reflect the required conversion from Fahrenheit to Celsius. Each fails to properly incorporate both the necessary subtraction of 32 and the correct multiplication factor, making them unsuitable for converting Fahrenheit temperatures accurately.
