What is the formula to convert Fahrenheit to Celsius?

The formula to convert Fahrenheit to Celsius is based on the linear relationship between the two temperature scales. To accurately convert a temperature value given in Fahrenheit to Celsius, you need to account for the offset of 32 degrees (which is the freezing point of water in Fahrenheit) and then divide the result by 1.8.

This means that after subtracting 32 from the Fahrenheit temperature, you are left with the corresponding temperature in Celsius in relation to the freezing point, which must then be accounted for by the factor of 1.8—this reflects the scale difference between Fahrenheit and Celsius. Therefore, the correct formula is C = (F - 32) / 1.8. This method of conversion ensures that you are accurately transforming the temperature reading from one scale to the other, allowing for precise calculations in practical applications, such as nursing or scientific research.
