  ° ' "
Decimal Degrees = °

One degree is equal to 60 minutes and 3600 seconds:

1º = 60' = 3600"

One minute is equal to 1/60 degrees:

1' = (1/60)º = 0.01666667º

One second is equal to 1/3600 degrees:

1" = (1/3600)º = 2.77778e-4º = 0.000277778º

For angle with d integer degrees m minutes and s seconds:

dº m' s"

The decimal degrees dd is equal to:

dd = d + m/60 + s/3600

Example
Convert 1 degrees30 minutes and 30 seconds angle to decimal degrees:

1º 30' 30"

The decimal degrees dd is equal to:

dd = d + m/60 + s/3600
dd = 1º + 30'/60 + 30"/3600 = 1.508333º
