EPSG:10280 RBEPP12 Grid
Projected system (Lambert Conic Conformal (2SP)) in use: UK - Reading to Penzance. 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.
