Tools
Coordinate conversion, distance calculation, geocoding, elevation, and other coordinate utilities. Shipped tools are linked; the rest are coming.
Coordinates to Address
Reverse geocoding: convert coordinates into a street address.
Address to Coordinates
Forward geocoding with confidence bands and ambiguous-result handling.
Distance Calculator
Geodesic distance between two points on WGS84 (Vincenty).
Midpoint Calculator
The geographic midpoint of two coordinates on an ellipsoid.
Bearing Calculator
Initial and final bearing between two coordinates.
Elevation
Elevation by coordinates — USGS 3DEP for US, OpenTopoData SRTM30m elsewhere.
My Location
Your current coordinates from the browser geolocation API.
Google Maps Coordinates
A guide-and-helper for reading coordinates out of Google Maps.
Coordinate Converter
Unified converter — DD, DMS, DDM, UTM, MGRS, Plus Code.
DMS ↔ Decimal Degrees
Convert between Degrees-Minutes-Seconds, Degrees-Decimal-Minutes, and Decimal Degrees in any direction.
UTM Converter
Lat/long ↔ UTM, with all 60 zones and band exceptions.
MGRS Converter
Lat/long ↔ MGRS at 1-100 km precision bands.
Plus Codes
Lat/long ↔ Open Location Code (Plus Code) — Google’s coordinate-format alternative.
ZIP to Coordinates
US ZIP code → centroid coordinates; with locality and county context.
Drop a Pin
Drop a pin on the map and copy a shareable URL with the coordinates baked in.
Time Zone by Location
IANA time zone from coordinates, with current UTC offset and DST status.
Sun Position
Sun azimuth, elevation, sunrise, sunset, and solar noon for a coordinate and date.
Magnetic Declination
The angle between true north and magnetic north, via the NOAA-NCEI World Magnetic Model.
