How do you convert Fahrenheit to degrees Celsius?

To convert Fahrenheit to degrees Celsius, the correct procedure is to subtract 32 from the Fahrenheit temperature and then multiply by 5/9. This process effectively transforms the temperature from the Fahrenheit scale to the Celsius scale.

The formula can be articulated as follows:

1. Take the Fahrenheit value.

2. Subtract 32 from it, which adjusts for the different zero points on the two scales.

3. Multiply the result by 5/9 to account for the difference in the size of the degree units between the two temperature scales.

Understanding this conversion is crucial for professionals in HVAC, as it allows them to accurately assess and manage temperature settings and calibrations across different systems that may use varying temperature measurements.
