# Degree Calculator

An online calculator to add and subtract two angles given in degrees, minutes and seconds (DMS) form.

## Table of Conversion Used in Degree Calculator

1 degree = 60 minutes
1 minute = 60 seconds.
1 degree = 3600 seconds

## Examples in Degree Calculator

Example: A1 and A2 are two angles given by A1 = 45� 34' 56" and A2 = 25� 45' 39". Find A1 + A2 and A1 - A2.
Let S = A1 + A2 = 45� 34' 56" + 25� 45' 39"
add degrees together, minutes together and seconds together
S = (45 + 25)� (34 + 45)' (56 + 39)" = 70� 79' 95"
We now need to convert 79' to degrees : 79' = 1� 19' and 95" to minutes: 95" = 1' 35" and substitute
S = 70� 79' 95" = 70� + (1� 19') + (1' 35") = 71� + 20' + 35"

Subtraction of two angles
With the subtraction and / or signed angles, it might be easier to convert each angle into seconds, subtract and convert again into degrees, minutes and seconds.
A1 = 45� 34' 56" = 45 � 3600 + 34 � 60 + 56 = 164096"
A2 = 25 � 3600 + 45 � 60 + 39 = 92739"
Let D = A1 - A2 = 164096 - 92739 = 71357"
Convert 71357" into dgrees
D = 71357" / 3600 = 19.8213888889� = 19� + 0.8213888889 � 60' = 19� 49' + 0.2833333333 � 60" = 19� 49' 17"

## How to Use the Degree Calculator

1 - Enter the size of the angles A1 and A2 in degrees, minutes and seconds (DMS) form, check your input and press "Add / Subtract". The outputs are the sum A1 + A2 and the difference A1 - A2 in two forms: degrees, minutes, seconds (DMS) and also in degrees decimal form.
Example of angles A1 and A2
22 � 34 ' 23 " (positive angle in DMS form)
-56 � 12 ' 45 " (negative angle in DMS form)
-0 � 23' 56" (negative angle less than 1 degree)

 A1 = 45 �     34 '     56 " A2 = 25 �     45 '     39 " Decimal Places = 4 A1 + A2 = �     '     " = � A1 - A2 = �     '     " = �
