How do I convert coordinates specified in seconds to the format used by my MFD?

While some third party products and applications (ex. Google Earth, etc.) support entry of and specification of waypoint latitude and longitude coordinates in DDD-MM-SS.SS format, Raymarine products exclusively support entry of and specification of waypoint latitude and longitude coordinates in the format DDD-MM.MMM format, where:

DDD - degrees of latitude or longitude
MM - Minutes of latitude or longitude
.MMM is fraction of a minute of latitude or longitude
SS.SS - Seconds of latitude or longitude
.SS is fraction a second of latitude or longitude

To convert seconds of latitude or longitude to a fraction of a minute for use within coordinates DDD-MM.MMM format, use the formula: .MMM = SS.SS / 60.

Example: Convert 42 47' 16.14" N to DDD-MM.MMM format; 16.14" / 60 = .269'; accordingly 42 47' 16.14" N = 42 47.269' N.
