This app is the first, and for now the only, app that can convert coordinates between 3800+ coordinate systems/datums. Not only the usual conversions between UTM, MGRS and the various WGS84 systems but also eg. between exotic types like Dominica 1945 / British West Indies Grid, Katanga 1955 / Katanga Lambert or NAD83 / Oklahoma South. Go to the support website to see an overview of all supported systems/datums. Features: - Over 3800 coordinate systems/datums to convert - When applicable, in- and output can be formatted D, DM or DMS - Results visible in OpenStreetMap when an internet connection is available - Export the converted coordinate to WhatsApp, Twitter, Email, Text message or just copy it to any other app
