Template:GBfromIEgrid/doc

A series of templates can be used to convert grid references in the Great Britain grid or the Irish grid between the standard letter-and-numbers format and the all-numeric format. {{GBfromIEgrid}} converts an Irish grid reference into the eastings and northings of the GB grid reference, roughly. (It is very much a simplified formula and does not provide an exact location because the two grids use projections on different bases, but it should be good enough for the mapping used here.)

The relevant templates are:

• {{IegridNum}}: coverts and Irish grid ref into all numeric format:
  • {{IegridNum|E}} gives the easting
  • {{IegridNum|N}} gives the northing
• {{GBfromIEgrid}}
