Luzon 1911 coordinate converter

Enter Luzon 1911 longitude and latitude, or PTM X and Y, then choose the correct Philippine zone. Results update as you type.

How to use

  1. Choose Geo to Grid or Grid to Geo, then select the Luzon 1911 zone used by your source data.
  2. Enter longitude and latitude in decimal degrees or DMS, or enter PTM X and PTM Y. Copy the compact or detailed result.

What the result means

PTM X and Y are projected grid coordinates in meters. Longitude and latitude are angular coordinates. The zone and datum must match the source; otherwise a plausible looking result can still be misplaced.

This converter works with Luzon 1911 geographic and grid coordinates. It is not a WGS 84 latitude/longitude to UTM converter, and it does not establish a legal parcel boundary.
