This question already has an answer here:

Im working with QGIS. When dividing a map with a grid I set in the paramters X=0.1 and Y=0.1. Could someone please explain what does that mean? I mean would the map be divided into 100mx100m squares? How do I know the exact measure in meters of each side of the square? Maybe its a silly question but its not that clear to me. Any help would be appreciated!

It depends on the units of the layers coordinate reference system.

  • If you have lat/lon degrees like WGS84, you get grid lines every 0.1 degree (i.e. 6 minutes).
  • If you have metres (as UTM and most other projected CRS do), your grid is every 10 centimetres.

Andre, thanks for your answer, how about for WGS84? – user20159 Aug 13 '13 at 16:38
That should be the degrees case. – AndreJ Aug 13 '13 at 17:44
