EPSG:31251 MGI (Ferro) / Austria GK West Zone
Projected system (Transverse Mercator) in use: Austria - west of 11°50'E. The full definition below, and conversion in one click.
EPSG publishes no simple transformation to WGS 84 for this datum: conversion works on the ellipsoid alone and can be off by tens of metres.
