EPSG:32161 NAD83 / Puerto Rico & Virgin Is.
Projected system (Lambert Conic Conformal (2SP)) in use: Caribbean - Puerto Rico and US Virgin Islands. 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.
