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 latitude and longitude to get a deterministic, reversible five-word grid code from this independent client-side demo.
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 converted to one unique integer derived from its row and column.
- Five words are selected as base-1,000 digits, providing enough unique codes for the entire grid.
- Copy the five-word demo code 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 custom human-readable 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.
- Encode field survey points as reversible five-word demo codes for easy radio communication.
