Solution 10578: Degree, Minutes, Seconds (DMS) Conversions with the TI-82.

How do I perform degrees, minutes, seconds (DMS) conversions using the TI-82?

The TI-82 recognizes a number in DMS when that number is entered using a single quote after each value. For example, to convert 15 degrees, 12 minutes and 8 seconds to decimal degrees, input 15'12'8' and press [ENTER]. The ' is accessed by pressing [2nd] [ANGLE] [2].

To convert a number that is written in decimal degrees to DMS, follow the example below:

Convert 12.2525 to Degrees, Minutes and Seconds

• Input 12.2525.
• Press [2nd] [MATRIX] to access the angle menu.
• Press [4] for the >DMS command.
• Press [ENTER].

The calculator will display 12º 15' 9".

Please see the TI-82 guidebook for additional information.
