What is the formula to convert Fahrenheit to Celsius?

The formula to convert Fahrenheit to Celsius is indeed C = 5/9(F - 32). This formula derives from the relationship between the two temperature scales and allows for accurate conversion between them.

In this formula, the temperature in Fahrenheit is first reduced by 32, which accounts for the offset between the two scales at the freezing point of water (32°F is equivalent to 0°C). After making this adjustment, multiplying the result by 5/9 scales the difference appropriately, as the size of the degree on the Fahrenheit scale is smaller than that of the Celsius scale. This conversion process is crucial for ensuring accurate temperature readings when switching between these two systems.

The other choices do not correctly reflect the conversion process needed to switch from Fahrenheit to Celsius. They either misrepresent the mathematical operations required or use the wrong constants. Understanding the conversion formula allows students to accurately transform temperature data and is an essential skill in both scientific contexts and everyday situations.
