To convert Fahrenheit to Celsius, what do you need to do after adjusting by 1.8?

To convert Fahrenheit to Celsius, the formula used is ( C = \frac{(F - 32)}{1.8} ). This means that you first need to subtract 32 degrees from the Fahrenheit temperature, which adjusts the measurement, and then divide that result by 1.8 to complete the conversion to Celsius.

In the context of the options, after adjusting by 1.8, the correct step involves subtracting 32 degrees from the Fahrenheit measurement; thus, the process begins by removing the 32-degree offset that distinguishes the Fahrenheit scale from the Celsius scale. This is a crucial step in ensuring that the temperature is properly translated across the two different systems of measurement.

The implication here is that the conversion requires understanding how the two scales relate, focusing on their inherent differences. By removing that constant difference of 32 degrees, you’re effectively homogenizing the comparison for a direct conversion to Celsius. Therefore, the approach of adding 32 degrees as indicated is counterproductive in this context, as it would lead you in the wrong direction.
