EPSG:2432 Beijing 1954 / 3-degree Gauss-Kruger CM 105E
Projected system (Transverse Mercator) in use: China - 103.5°E to 106.5°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.
