Which of the following formulas converts Celsius to Fahrenheit?

The formula that converts Celsius to Fahrenheit is derived from the relationship between the two temperature scales. In this case, the correct formula is represented as ( F = (9/5)C + 32 ).

This conversion works as follows: to convert a temperature given in degrees Celsius (C) to degrees Fahrenheit (F), you first multiply the Celsius value by ( \frac{9}{5} ) (which is the ratio of the differences between the freezing and boiling points of water in Fahrenheit and Celsius). After this multiplication, you then add 32, which accounts for the difference in the starting points of the two scales — where 0 degrees Celsius is equivalent to 32 degrees Fahrenheit.

In contrast, the other formulas provided either incorporate incorrect multiplication factors, misplace the addition or subtraction of 32, or entirely misrepresent the relationships between Celsius and Fahrenheit. Hence, using ( F = (9/5)C + 32 ) allows for accurate conversion from Celsius to Fahrenheit.
