Convert Wikipedia coordinates ({{coord}}) into decimal

Question

How can I convert Wikipedia coordinates coming directly from source code into decimal ones?

Input: DMS coordinates

{{coord|33|21|30.5|S|70|41|50.4|W|scale:5000}}

Desired output:

-33.358472, -70.697333

Should I use geoconvert or try to do it with awk?

Answer 1

D + M/60 + S/3600

Is the formular to convert from DMS to Decimal. Have you been able to parse the input to be able to get the DMS values on their own, or is this what you are struggling with?
