The degree sign (the small circle after a series of numbers) most commonly represents units of temperature (both Celsius and Fahrenheit), but it can also refer to geographic coordinates (such as longitude and latitude). Most keyboards do not have a specific key used to type this symbol. However, you can use keyboard shortcuts for Windows PCs and Mac systems to type the symbol.

Position your cursor after the digits where you want to use the degree symbol. For example, if you want to type "34º," position your cursor to the right of the "4."
If using a PC, hold down the "Alt" button, and immediately type the digits "1-6-7" on your keyboard number pad. The degree symbol will display in the desired position.
Make the degree sign on a Mac by using the command "Option" + "Shift" + "8."
