What is the formula to convert Celsius to Fahrenheit?

The formula to convert Celsius to Fahrenheit is expressed as F = (C x 9/5) + 32. This equation effectively converts the temperature measured in degrees Celsius (C) into degrees Fahrenheit (F).

To break down the formula:

1. The factor of 9/5 represents the proportional relationship between the Celsius and Fahrenheit scales. To understand this, note that the freezing point of water is 0 degrees Celsius and 32 degrees Fahrenheit, while the boiling point is 100 degrees Celsius and 212 degrees Fahrenheit. The 9/5 ratio reflects the difference in size of the two temperature intervals.

2. Adding 32 is necessary to adjust the starting point of the scale from the Celsius value to its equivalent Fahrenheit value, given that the two scales have different reference points (where 0 in Celsius does not equal 0 in Fahrenheit).

This conversion is crucial in various practical applications including healthcare settings, where temperature measurement is key in diagnosing and monitoring patients. The other formulas provided do not accurately reflect the conversion process, either by rearranging the terms incorrectly or by not converting Celsius to Fahrenheit properly.
