When converting Fahrenheit to Celsius, which equation is correct?

The conversion from Fahrenheit to Celsius utilizes the formula where you subtract 32 from the Fahrenheit temperature and then divide the result by 1.8. Therefore, the correct equation for converting Fahrenheit to Celsius is represented in the first option.

To clarify how the process works: you start with a Fahrenheit temperature, subtract 32 to account for the difference between the two temperature scales, and then divide by 1.8 to convert to Celsius. For instance, if you have 68 degrees Fahrenheit, you would perform the calculation as follows:

1. Subtract 32: 68 - 32 = 36

2. Divide by 1.8: 36 / 1.8 = 20 degrees Celsius.

The other formulas provided relate to converting Celsius to Fahrenheit or incorrectly state the operations required for the conversion. One might mistakenly choose a different formula if they are interpreting the direction of conversion or missing the specific mathematical operations necessary in the conversion process.
