Example

Convert degrees minutes seconds to decimal degrees:

1. Take the decimals (digits after the point)
2. Divide them by 60
3. The full number (before the point) are the minutes
4. The rest (decimals, after the point) should be divided again by 60
5. These are the seconds

12.456º
456
456 / 60 = 7.6
7'

6 / 60 = 10

10" --> 12º 7' 10''

Convert degrees minutes seconds to decimal degrees:

1. Take the seconds
2. Divide them by 60
3. Add the minutes
4. Divide by 60
5. These are the decimals of degrees

1º 13' 46.56"
46.56
46.56 / 60 = 0.776
0.776 + 13 = 13.776
13.776 / 60 = 0.2296
.2296
--> 1.2296º
