What is the formula to convert Fahrenheit to Celsius?

The formula to convert Fahrenheit to Celsius is derived from understanding the relationship between the two temperature scales. The correct formula, which is represented in the selected answer, states that you subtract 32 from the Fahrenheit temperature and then divide the result by 1.8 to find the corresponding Celsius temperature. This accurately reflects the way the scales are defined relative to each other.

To break it down further, the conversion is based on the freezing and boiling points of water. Water freezes at 32 degrees Fahrenheit and 0 degrees Celsius, and it boils at 212 degrees Fahrenheit and 100 degrees Celsius. The difference in degree increments between the two scales necessitates the division by the factor of 1.8, which indicates how many Fahrenheit degrees correspond to a single Celsius degree change.

Thus, using this formula allows for an accurate transformation of a temperature from Fahrenheit to Celsius, facilitating better scientific communication and comparisons across different contexts where temperature measurement is key. This understanding is vital for a variety of applications, from weather reporting to scientific research, where precise temperature readings are crucial.
