Convert between Degrees and DMS with the TI-84 Plus Calculator

The functions housed in the TI-84 Plus calculator's Angle menu allow you to convert between degrees and DMS (degrees, minutes, and seconds) and between DMS and degrees. You can also override the angle setting in the Mode menu of the calculator when you use these functions.

  2. If necessary, press [2nd][MODE] to access the Home screen.
