Online Conversions - basic

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

Use the vertical datum conversion to convert between New Zealand vertical datums - see instructions for carrying out height conversions for more information.

Use the detailed online conversion to choose from a wider range of datums, projections and height systems. It also allows a variety of input and output formats (including bulk options) that are more suited to users with an understanding of coordinate and height conversions.

    Conversion date
Specifies the date at which the conversion applies. Many conversions, for example from NZGD2000 to ITRF2008, depend upon the date. The date can be entered either as as decimal year (eg 2000, 2013.5), a day/month/year format (22 8 2012, 5 Jan 1995) or the word "now" for the current date.
