Another tip to remember is that the Internet is a global medium, so tailor your contributions to a global audience. For example, if you post, “It’s 40° outside,” some people are going to wonder whether you are expressing how cold it is or how hot it is. Try to remove the ambiguity by indicating whether it is 40 °F or 40 °C. If you are really feeling generous, provide a conversion, e.g., 40 °F (4 °C) or 40 °C (104 °F).
