Free Coordinate & GPS Tools

Convert coordinates between formats, geocode addresses, and reverse-geocode GPS points — all free, most running instantly in your browser with no sign-up.

Location Tools

Find your location, measure distances, and explore coordinates on a map — free and instant.

What's My Location Map

Your current location, GPS coordinates and address on a map — with an IP fallback if you decline access.

Open tool →
Distance Calculator Map

Great-circle distance and bearing between two lat/long points, shown on a map.

Open tool →
Distance From Me GPS

How far is it from your current GPS location to any city, address or coordinate?

Open tool →
What County Am I In? GPS

Find what county (or parish/borough) you're in right now using your device GPS — US Census data.

Open tool →
What State Am I In? GPS

Find what state, province or region you're in right now using your device GPS — works worldwide.

Open tool →
Elevation Finder API

Find the height above sea level of any lat/long (or your current location) — SRTM data, 30 m resolution.

Open tool →
Bearing & Azimuth Map

Initial and final bearing (azimuth) between two coordinates, with compass direction.

Open tool →
Destination Point Map

Given a start, bearing and distance, calculate where you arrive — the inverse of bearing.

Open tool →
Midpoint of Two Coords Map

Great-circle halfway point between two lat/long coordinates, with a map.

Open tool →
Centroid of Points Map

Find the geographic centre of gravity of any number of lat/long points, plus their bounding box.

Open tool →
Bounding Box Generator Map

Generate a lat/long bounding box from a center point and radius — outputs corners + GeoJSON.

Open tool →
Antipodes Calculator Map

Find the point on the opposite side of the Earth — "if you dug straight down, where would you come out?"

Open tool →
Geographic Center API

Find the geographic centre of any country, state, or region from its bounding box.

Open tool →
City → Lat/Long API

Get the coordinates of any city, town or village worldwide — disambiguate with the country.

Open tool →
Coordinate Validator Map

Validate a lat/lng pair (range, precision, plausibility) and generate random valid coordinates.

Open tool →
Sunrise & Sunset Map

Sunrise, sunset, solar noon and twilight times for any coordinate — NOAA-accuracy, DST-aware.

Open tool →
Timezone from Coordinates API

Get the IANA timezone, UTC offset, abbreviation and DST status for any lat/long.

Open tool →

Coordinate Converters

Convert between coordinate formats right in your browser — no upload, no sign-up, works offline.

DMS ↔ Decimal Instant

Convert degrees/minutes/seconds to decimal degrees and back, with the formula.

Open tool →
Lat/Long → DMS Instant

Convert decimal degrees to DMS (degrees/minutes/seconds) and decimal minutes (DDM).

Open tool →
UTM ↔ Lat/Long Instant

Convert UTM zone, easting and northing to latitude/longitude (WGS84) — and back.

Open tool →
Plus Code ↔ Lat/Long Instant

Decode a Plus Code (Open Location Code) to coordinates, or encode coordinates to one.

Open tool →
Geohash Converter Map

Decode a geohash to coordinates or encode lat/long to a geohash, shown on a map.

Open tool →
MGRS ↔ Lat/Long Map

Convert Military Grid Reference System coordinates to latitude/longitude and back.

Open tool →
Web Mercator ↔ Lat/Long Map

Convert EPSG:3857 X/Y metres to lat/long (EPSG:4326) — the projection every web map uses.

Open tool →
ECEF (X/Y/Z) ↔ Lat/Long Instant

Convert Earth-Centered Earth-Fixed Cartesian coordinates to lat/lng/height (WGS84, Bowring).

Open tool →
Decimal Minutes (DDM) Map

Convert decimal degrees to degrees decimal minutes — the marine and aviation GPS format.

Open tool →
Address → Plus Code API

Geocode any street address or place name to a Google Plus Code. Powered by our free geocoder.

Open tool →
Maidenhead Grid ↔ Lat/Long Map

Convert lat/long to a Maidenhead (QTH) grid square for ham radio, and back.

Open tool →
EPSG / CRS Transformer Instant

Reproject coordinates between WGS84, Web Mercator, all UTM zones, and national grids (proj4).

Open tool →
Coordinate Format Detector Instant

Paste any coordinate — decimal, DMS, UTM, MGRS, Plus Code or geohash — auto-detect and convert to lat/long.

Open tool →
Batch Coordinate Converter CSV

Paste a whole list of coordinates (any format, mixed) and get a clean CSV of decimal lat/long.

Open tool →
WKT ↔ GeoJSON Instant

Convert Well-Known-Text geometry to GeoJSON and back — Point, Line, Polygon, Multi and Collections.

Open tool →
GPX ↔ KML ↔ GeoJSON File

Convert GPS track files between GPX, KML and GeoJSON — waypoints, tracks, routes and polygons.

Open tool →
CSV → Map Plotter CSV

Paste a CSV of lat/long points and plot them on a map — auto-detect columns, colour by any field.

Open tool →

Unit Converters

Quick conversions between the units used in mapping, surveying, and navigation.

Geocoding Tools

Turn addresses into coordinates and coordinates into addresses, powered by the free LatLng API.

Developer APIs

Free-tier REST APIs behind the tools above — 3,000 requests/day, no credit card.

All the coordinate tools you need, in one place

Working with locations means constantly switching between formats. Paper maps and GPS units use degrees, minutes, seconds; surveyors and GIS use UTM; Google Maps shows Plus Codes; and every API and database wants plain decimal degrees. These free tools convert between all of them — and turn addresses into coordinates and back.

  • No sign-up, no cost. The converters run entirely in your browser; the geocoders use the free LatLng API tier.
  • Accurate. Conversions use standard WGS84 formulas and the official Open Location Code algorithm.
  • Private. Coordinate conversions never leave your device.

Need to do this at scale in code? Every tool here is backed by a simple REST API — get a free API key for 3,000 requests per day.
