Common mistakes with Kertau 1968 / Kedah and Perlis Grid
- Easting and northing swapped. In Kertau 1968 / Kedah and Perlis Grid the middle of the grid is near easting -31,146.47 and northing -7,152.14. If your easting column holds numbers like -7,152.14, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. Kertau 1968 / Kedah and Perlis Grid is in metres. Coordinates copied from a drawing in feet must be converted first, or every point moves outwards from the grid's origin.
- Forgetting the datum. Kertau 1968 / Kedah and Perlis Grid is not on WGS 84: published 3-parameter shift (typically a few metres). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
- Points outside the grid's area. Kertau 1968 / Kedah and Perlis Grid is meant for Malaysia - West Malaysia - Kedah and Perlis. Points well outside that area convert with growing error; the converter flags them so you can choose the right grid.
- A local site grid. If every point is off by the same distance and direction, the drawing may be on a local site grid. Calibrate on three or more known control points instead.
