Online Conversions

Convert between pre-selected geodetic datums and projections using default input and output parameters.

Use the basic online conversion to choose between pre-selected datums and projections using default input and output parameters.

Read instructions for carrying out height conversions to transform heights between vertical datums.



Input coordinate system

   
   
Coordinate order
    North/East
    East/North

Choose whether input coordinates have northing (latitude) or easting (longitude) coordinates first.
   
Coordinate format
    Degrees/minutes/seconds
    Degrees/minutes
    Decimal degrees

Choose whether latitudes and longitudes are entered as degrees, minutes, and seconds (eg 41 30 25.3 S) degrees and minutes (eg 41 30.42 S) or decimal degrees (eg -41.50703). (This is ignored for projection coordinate systems)
   
Height coordinate system

Select the height coordinate to enter - none, ellipsoidal, or an orthometric system. Note: Ellipsoidal heights are in terms of the ellipsoid of the input coordinate system.

Output coordinate system

   
   
Coordinate order
    North/east
    East/north

Choose whether output coordinates have northing (latitude) or easting (longitude) coordinates first.
   
Coordinate format
    Degrees/minutes/seconds
    Degrees/minutes
    Decimal degrees

Choose whether latitudes and longitudes are output as degrees, minutes, and seconds (eg 41 30 25.3 S), degrees and minutes (eg 41 30.42 S) or decimal degrees (eg -41.50703) (This is ignored for projection coordinate systems)
   
Height coordinate system

Select the height coordinate to calculate - none, ellipsoidal, an orthometric height coordinate, or geoid heights. Note: Ellipsoidal and geoid heights are in terms of the ellipsoid of the output coordinate system.

General options

    Input format
    Text box entry
    Free format entry
        delimiter 
Text box entry provides an entry field for each coordinate to be converted. Free format entry provides a single entry field into which all the coordinates can be typed. (This is more useful if the coordinates are being copied from the clipboard, for example) For free format text specify the character to use to separate input columns.
   
Output format
    Formatted
    Unformatted
        delimiter 

Choose formatted to display the output coordinates as a normal web page, or unformatted to return the coordinates in a simple form suitable for copying to spreadsheets or other documents. For unformatted text specify the character to use to separated the columns.
   
Output precision (metres)
    1.0
    0.1
    0.01
    0.001
    0.0001

Select the approximate precision used for the output coordinates. Note that this affects only the number of digits displayed, not the actual accuracy of the coordinates.
   
Points have names/codes
    No
    Yes

Select this option to enter a point name (or code) for each coordinate
   
Show input coordinates in the output
    No
    Yes

If this option is selected the input coordinates will be copied in the output.
