In the degrees, minutes, seconds (or DMS) format, the same angle is 33 degrees, 30 minutes. The HP 9g can work with angles in either measurement system and provides the DRG (X) and DMS (~z) menus to convert between them. It also has the DMS function ((~z„=) which is useful when converting between the two formats of angles in degrees.

HP 9g Converting Angles and Times The entry line contains 25º. When this is evaluated by pressing =, the HP 9g will convert 25º into the current angle unit, i.e. radians. Answer: 0.436332313 radians. Example 2: Convert 25º into grads.

Example 7: Convert an angle of 118º 27’ 59’’ into decimal degrees. Solution: On the HP 9g there is no specific function to convert DMS into decimal degrees, because such conversion is done automatically when processing the entry line, i.e. after pressing the = key. The º, ‘ and ‘’ symbols are in the DMS menu: 118~z=27~z†=59~z††=...
