Good to know
- This is a southern-hemisphere grid: northings start at 10,000,000 m at the equator.
- Pick the UTM zone by longitude. Points outside the zone's area of use are flagged after conversion.
- Datum: Treated as WGS 84, no shift (the datums agree to about a metre or better).

Common mistakes with PNG94 / PNGMG94 zone 55
- Easting and northing swapped. In PNG94 / PNGMG94 zone 55 the middle of the grid is near easting 500,553.69 and northing 9,375,484.95. If your easting column holds numbers like 9,375,484.95, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. PNG94 / PNGMG94 zone 55 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. PNG94 / PNGMG94 zone 55 is not on WGS 84: treated as WGS 84, no shift (the datums agree to about a metre or better). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
- Points outside the grid's area. PNG94 / PNGMG94 zone 55 is meant for Papua New Guinea - between 144°E and 150°E, onshore and offshore. 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.
