Grid to Geographic

Use Krueger's n-series formulae to project an easting, northing, and zone (a grid coordinate) to a latitude and a longitude (a geographic coordinate).

Note: Krueger's n-series formulae are more accurate versions of Redfearn's formulae.

Map Grid of Australia 2020 (MGA2020) is a UTM projection. The GRS80 ellipsoid must be selected to use MGA2020, and calculations are only valid within the Geodetic Datum of Australia 2020 extent.

For more details see the GDA2020 Technical Manual.
