About this demo
Grid step: 0.000027° (~3 m at equator). Words are picked from a 1,000-word vocabulary using deterministic index arithmetic. Results are stable but do not match the official what3words API.

Summary
Enter a decimal latitude and longitude to get a deterministic three-word location address — a client-side demo of the what3words concept.
How it works
- Enter a decimal latitude (−90 to 90) and longitude (−180 to 180).
- The tool quantizes the coordinates into a grid of roughly 3-meter squares (0.000027° steps).
- Each grid cell is mapped to a unique pair of indices derived from its row and column.
- Three words are selected from a 1,000-word vocabulary using those indices, producing a stable address.
- Copy the three-word address with one click for sharing or reference.
Use cases
- Demonstrate the what3words geocoding concept to students and colleagues.
- Generate human-readable location codes for internal project coordinates.
- Test mapping applications that accept three-word-style location identifiers.
- Explore how grid-based geocoding handles edge cases near the poles and date line.
- Share a memorable location code without exposing raw numeric coordinates.
- Quickly encode field survey points as word triples for easy radio communication.
