How can i change the temperature from deg Fahren to deg C

Cars are identified with a proper sequence contrary what the common teen texting slanglish code prescribes. First the year. 2008. Then the brand or make: Honda. Then the model name or letters or numbers as registered by the manufacturer. In this case CRV. This car is a 2008 Honda CRV and not ever a Honda crv 2008. Please text, Tweet, whatever to all of your friends and enemies. English grammar. Celsius. Not "Celsuis." First word of all sentences is capitalized. All sentence end with a proper punctuation mark. You failed in both of these requirements. The pronoun, I, must be capitalized always. Next, ever hear of the owner's manual that is in each car with all of the instructions an owner needs?

First I'm french educated and i'm texting from my mobile. I need an answer for my question, not an English class from you, if you don't know how to do it, don't bla bla bla… Too much.
For the Manual, i already check it you Clever boy, nothing mentioned inside it about that.
