Coordinate Converter: Lat/Long, DMS, UTM, MGRS & Distance

A coordinate converter for GIS users, surveyors, hunters, hikers and search-and-rescue teams that lives in your toolbar and works offline. Paste a coordinate in almost any format, or a Google Maps, OpenStreetMap or Bing link, and get every other format at once. FREE, FOREVER • Convert: decimal degrees, degrees-minutes-seconds and degrees-decimal-minutes with N/S/E/W letters or signs, plus UTM with scale factor and grid convergence • Reads Google Maps, OpenStreetMap and Bing links, and opens any result in Google Maps or OpenStreetMap • UTM to latitude/longitude from zone, hemisphere, easting and northing, with the Norway and Svalbard zone exceptions PRO, $1.99 ONCE (free for your first 7 days) • MGRS both ways, from 10 km to 1 m precision, with the WGS84 100 km square lettering • Distance and bearing: Vincenty ellipsoidal distance, initial and final bearing and geodesic midpoint, with haversine for comparison • Batch convert: paste a list of coordinates or MGRS references and copy a spreadsheet-ready table • Copy clean results into reports, GIS or field notes WHY PROFESSIONALS USE IT • UTM by the Krüger series, round-trip accurate to well under a millimetre • Checked against published worked examples (Snyder's transverse Mercator example, the Geoscience Australia Vincenty example) • Works offline. Nothing you paste leaves your computer PRIVACY Nothing you enter leaves your computer. No tracking, no ads, no account. The only network call is the optional payment check through ExtensionPay. All conversions assume WGS84. Coordinates on other datums (such as NAD27) must be transformed first. Not for navigation where life safety depends on it without an independent check.
