What are you talking about? 33C is 91.4F and 34C is 93.2F So what 4 numbers? Fahrenheit didn't make sense even at it's inception. It's based on a false reading of human temperature, and the freezing point of an ammonium chloride solution. Which is just completely random. It's not a frame of reference to any normal human being.
And 0 is not an exact number, but 32 is? Whaat?
