    Thank you very much Wilfried for the formula


    Now I've got another problem... I'm not sure about the format of coordinates that I need to convert to dd°ddddd :

    the coordinate that I have is :

    latitude = 4641.67731N
    longitude = 00201.77373E

    Does anyone know what is this format ?
    To me, I would say :

    Latitude: degrees=46 minutes=41 but seconds cannot be 67.731??
    Longitude: degrees=02 minutes=01 but secondes cannot be 77.373?


    Thank you

    Hi,

    This looks NMEA 183 format. However then it should be with a comma ',' just before the N or E. it should be:

    latitude: ddmm.ffff
    longitude: dddmm.ffff

    where ffff the minute fractions are. I mean minute is just a float, like this:
    5010.1234
    is degree 50 latitude
    minute: 10.1234

    Oupss... I've just understood

    formula to convert dd°mmfffff' to dd.dddddd° is the following:
    degrees + minutes/60
