The Fahrenheit symbol contains a degree symbol followed by the letter F. Since the degree symbol doesn't have a dedicated key, you'll need to use ASCII code to insert it in a document or other text field. All you need is the "Alt" key on your keyboard and the correct code. Note that you must enter the code using the numeric keypad.

Inserting the Degree Symbol

Before you begin, ensure the insertion cursor is positioned at the position you want the symbol to appear. Hold "Alt" and then type "248" using the numeric keypad. Release the "Alt" key to insert the degree symbol. Hold "Shift" and press "F" on your keyboard to insert the "F" letter immediately after the degree symbol.

On a Mac, press "Shift-Option-8" to insert the degree symbol.
