GPS Coordinate Converter

This converts a latitude and longitude between the three ways they get written: decimal degrees, degrees with decimal minutes, and degrees minutes seconds. Paste a coordinate in any of those forms and it returns all three, or type the degrees, minutes and seconds into separate boxes if that is what you have. It also tells you what each decimal place is worth on the ground at that latitude, which is the part that decides how many digits you need to keep. Everything is WGS84, the datum a phone and a handheld GPS report, and there is no map or place lookup behind it.
