EPSG:6633 NAD83(PA11) / Hawaii zone 3 (ftUS)
Projected system (Transverse Mercator) in use: USA - Hawaii - Oahu - onshore. 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.
