In the equation for converting Fahrenheit to Celsius, what is the first step?

To convert Fahrenheit to Celsius, the first step in the mathematical equation is to subtract 32 from the Fahrenheit temperature. This step is necessary because the two scales have different zero points and increments. The Fahrenheit scale defines freezing at 32°F, while Celsius defines it at 0°C. Therefore, to start converting a Fahrenheit temperature to its Celsius equivalent, you must first adjust the value by removing the offset of 32°F.

After subtraction, the next steps involve multiplying the result by 5/9 to account for the different scales. Understanding the significance of the subtraction step is crucial for accurately conducting the temperature conversion process.
