The ASCII (Alt+number) for the square root symbol (√) in Windows


How do I type the square root symbol (√) in Windows?

Best Answer

  • In short it's ALT + 251 (note, no preceding zero)

    Unicode it is U-221A

    If that doesn't work then:

    Press and hold down the Alt key.
    Press the + (plus) key on the numeric keypad.
    Type the hexidecimal unicode value (221A).
    Release the Alt key.
