What is the formula to convert Fahrenheit to Celsius?

The formula to convert Fahrenheit to Celsius is indeed given by C = (F - 32) / 1.8. This formula is derived from the linear relationship between the two temperature scales.

When converting from Fahrenheit to Celsius, it is necessary to first subtract 32 from the Fahrenheit temperature, as 32 degrees Fahrenheit is equivalent to 0 degrees Celsius. This adjustment accounts for the difference in the starting points of the two scales. The next step is to divide the result by 1.8, as the degree sizes differ between the two scales; one degree Celsius is equivalent to 1.8 degrees Fahrenheit.

Thus, applying this formula allows one to accurately convert a temperature value from the Fahrenheit scale to the Celsius scale, making it a vital tool for anyone working with temperature measurements in contexts where both systems are used. Understanding this conversion is crucial for water operation professionals who often need to reference temperature in different units for compliance, monitoring, and treatment processes.
