EPSG:20049 SIRGAS-Chile 2021 / UTM zone 19S

Projected system (Transverse Mercator) in use: Chile - 72°W to 66°W. 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.
