Degrees - Minutes - Seconds   angle calculator

This calculator is used to add and subtract angles in the form Degrees - Minutes - Seconds (DMS). Each degree is divided into 60 minutes, and each minute further divided into 60 seconds. This form is used in astronomy and defining latitude and longitude.

Example 34° 24' 16''

This is read as "34 degrees 24 minutes 16 seconds".

° ' ''


The calculator adds or subtracts input values from the running total in the top window.

  • Enter a value in three parts: the degrees in left field, minutes in the middle, and seconds in the right field.
  • Press "enter" to enter the input value into the running total, replacing what was there.
  • OR: Press either the Plus or Minus button to add/subtract it from the running total.
  • Negative inputs should have a minus sign in front of the degrees: -12° 23' 31''
  • Small negative numbers (less than one degree) are entered with -0 in the degrees field:
    Example: -0° 23' 0''

Automatic conversion to decimal degrees

Whenever a result is calculated it is also converted to decimal degrees. This is displayed just below the result window

... I have a small favor to ask. Over the years we have used advertising to support the site so it can remain free for everyone. However, advertising revenue is falling and I have always hated the ads. So, would you go to Patreon and become a patron of the site? When we reach the goal I will remove all advertising from the site.

It only takes a minute and any amount would be greatly appreciated. Thank you for considering it!   – John Page
