Example coordinates

A WGS 84 point at longitude 47.51°, latitude 29.31° (inside the area of use) has these coordinates in EPSG:24600:

Computed with PROJ using the EPSG default operation: axis order change (2D) + Inverse of KOC to WGS 84 (1) + Iraq zone.
AxisValueUnit
E1,743,824.706m
N815,336.231m

At this point the projection scale factor is 1.00031077 and the grid convergence is +1.348622°.

A PROJ string cannot carry every EPSG detail (axis order, datum ensemble, transformations). Prefer WKT2 or the EPSG code itself.

Datum shift from KOC to WGS 84 (1) (EPSG accuracy 1 m), the best single Helmert operation for this area of use. Where PROJ prefers a grid-based or multi-step operation (see the table above), results can differ by up to that operation's accuracy.

FAQ

What is EPSG:24600?

EPSG:24600 (KOC Lambert) is a projected coordinate reference system on the Kuwait Oil Company datum using the Lambert Conic Conformal (1SP) method, with coordinates in metres. Area of use: Kuwait - onshore.

Where can EPSG:24600 be used?

Its area of use is: Kuwait - onshore.

Is EPSG:24600 in metres or degrees?

EPSG:24600 is projected, so coordinates are easting and northing in metres, not degrees.

How do I convert EPSG:24600 to latitude and longitude?

Transform from EPSG:24600 to EPSG:4326 (WGS 84). In GeoCAD Bridge open the coordinate converter with EPSG:24600 preselected, enter easting and northing, and choose WGS 84 as the target.

How accurate is the transformation from EPSG:24600 to WGS 84?

The most accurate EPSG transformation listed here is “axis order change (2D) + KOC to WGS 84 (1) + axis order change (2D)”, with a stated accuracy of 1 m for Kuwait - onshore.. Always check the area of use before applying it.
