Convert GPS coords from one format to another, use in iframe!

Simple page that has two input fields, lat/long. When you click submit, it will convert the coords you put in to other GPS coord formats and display the point on a map. So it would convert formats like: 39.123456 vs N 39° 12.345 Needs to be flexible and work if the ° is there or not. And work if the use input "N" or "N " (with/without space) Plus modify a map we recently had coded. #1 Add in a place for us to place our Google Maps API Key. #2 Add in OpenStreetMaps Layer Option. We would also like to add in OpenCycleMaps and OpenStreetMaps B&W (Black & White).
