How can I type unit symbols such as m2, °C, and µm?
Instructions for typing special characters such as exponents, the degree symbol, and the Greek letter mu depend on your computer’s operating system and what particular software you’re typing “at,” among other things. Following is some general advice; consult your computer’s “help” system or other documentation for further assistance. You might find, for example, that your keyboard lets you redefine keys to make it easier to type commonly used special characters, or your word processing software might have additional ways to enter special characters (e.g., Microsoft Word’s “autocorrect” feature).
