The relationship between degrees Celsius (°C) and degrees Fahrenheit (°F) is not a simple linear relationship where adding the temperature values in Celsius will result in double the temperature value in Fahrenheit.
The conversion formulas between Celsius and Fahrenheit are as follows:
°F = (°C × 9/5) + 32
°C = (°F - 32) × 5/9
These formulas involve multiplication and addition/subtraction, which means the temperature scales are not directly additive. The addition of temperatures in Celsius does not translate to the addition of temperatures in Fahrenheit.
So, saying that 0 degrees Celsius + 0 degrees Celsius equals 64 degrees Fahrenheit is incorrect. Using the conversion formula, if you add 0 degrees Celsius + 0 degrees Celsius, you get 32 degrees Fahrenheit, not 64 degrees Fahrenheit.
The conversion formulas are necessary to convert temperatures accurately between Celsius and Fahrenheit due to the different scales and temperature intervals used in each system.
