EPSG:3353 Mhast (onshore) / UTM zone 32S

Projected system (Transverse Mercator) in use: Africa - Angola (Cabinda) and DR Congo (Zaire) - coastal. 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.
