Coordinates to S2 Cell Converter
Coordinates to S2 Cell Converter with Cell ID, token, level, boundary, and center coordinates.
How to use
- Enter a coordinate and S2 level (0–30) to get its Cell ID, token, and boundary.
- Click a Parent, Child, or Neighbor cell to jump to it and recompute everything.
- Click the map to set the input coordinate directly, or use the current map center.
- Batch (CSV) tab converts many coordinates to S2 cells at once.
Lower level = larger cells, higher level = smaller cells.

What is S2?
S2 Geometry divides the Earth's surface into a hierarchy of cells for efficient spatial indexing. Each cell has a parent-child relationship, and higher levels subdivide into smaller cells.

How it works
- Enter coordinates or an S2 Cell ID/token for this direction.
- Review the converted cell or center coordinates.
- Inspect the S2 boundary on the map.
Supported range
Supports S2 levels 0 through 30 and decimal Cell IDs or canonical tokens.
Important notes
Decoded coordinates represent the S2 cell center.
