About the Lambert Conformal Conic family
KOC Lambert uses the Lambert Conformal Conic projection — a cone-based, angle-preserving grid well suited to territories that stretch east–west, defined by one or two standard parallels. It is common for national mapping and for oil-and-gas grids across North Africa and Arabia.
Scale is true along the standard parallel(s) and grows away from them; for precise distance work reduce ground distances to grid using the point scale factor. Confirm both standard parallels and the datum before trusting imported coordinates.

FAQ
- What is EPSG:24600?
- It is the coordinate system “KOC Lambert”, a Projected (metres) system in the Lambert Conformal Conic family, identified worldwide by the code EPSG:24600.
- What datum does it use, and how accurate is it?
- It is based on the a=6378249.145 ellipsoid and it carries Helmert parameters to WGS84. The residual at the test point is about ±0.1 m versus PROJ; for centimetre work use a geodetic adjustment service.
- Where is this system used?
- It is used in Kuwait. This page shows its area of use as a coordinate rectangle above.
- How do I convert EPSG:24600 to WGS84?
- Use the free coordinate converter above (preloaded with this system) to convert to WGS84, UTM, or any other system, within a ±0.1 m residual.
