EPSG:2313 Kousseri / UTM zone 33N
Projected system (Transverse Mercator) in use: Cameroon - N'Djamena area. 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.
