Geohash Converter
Convert between coordinates and geohash strings.
How to use
- Enter a coordinate and precision (1–12 characters) to get its geohash.
- Or paste a geohash to decode it back into a coordinate and bounding box.

Bidirectional Geohash Conversion
Encode coordinates as a 1–12 character Geohash or decode a Geohash to its center and bounding box. Inspect cell size and neighbors by precision.
Pick a precision to match the task — 5 characters covers city scale, 9 or more narrows to a single building. Encode and decode results are checked against independently published example values (such as Wikipedia's), which catches a shared error in both directions that a round-trip test alone would miss.
How to use it
- Enter coordinates to encode, or a geohash string to decode.
- Choose a precision from 1 to 12 characters.
- Check the cell size and its neighbors on the map.
Frequently asked questions
How much area does one geohash character represent?
Each added character shrinks the cell roughly 4–8x — 5 characters covers kilometers, 9 narrows to meters.
Why verify against a Wikipedia example too?
A round-trip test alone can't catch encode and decode sharing the same wrong convention — matching an independently published value rules that out.
