I was very confused with my QGIS 2.18.14,

i'm pretty sure that i used correct coordinate system, WGS84/UTM 48N, and the coordinate also said so. But why when i set the grid. The grid coordinate is not showing real coordinate? I found that the grid not change while i move item content(the point).

what's wrong?

showing that the coordinate in the system:

showing that the grid failure to not showing the coordinate: enter image description here


I’ve seen something similar just now using a different UTM projection

This can happen if

  • You set the grid to match your UTM - EPSG:32648
  • You use format “Decimal with suffix”
  • You used “cm” or “mm” as the interval units

I think the last one might be the problem. All the coordinates are positive, and start in the bottom left.

Note that “mm” and “cm” refer to the print size, not real world units, so will vary according to scale.

You can also get odd results mixing degrees formatting with a UTM grid.

Here's an example showing the same results:-

enter image description here

If you want the grid to be in degrees, use WGS84 for your grid. If you want it to be in meters, to match the UTM coordinates, use the UTM projection and set the format to “Decimal”

What you can’t do, unfortunately, is specify a map interval of “degrees” on a UTM grid - just map units (always meters for UTM), cm or mm.
