About this conversion
Convert what3words addresses to WGS 84 latitude and longitude using your what3words API key. Each address labels a 3 metre square.
Frequently asked questions
What input is accepted?
Enter exactly three words separated by full stops. Surrounding whitespace is trimmed, but missing words or separators are not invented.
What output will I receive?
By default, results show WGS 84 latitude first and longitude second in decimal degrees. Select Reverse coordinate order to show longitude first. Displayed decimal places do not add accuracy to the source square.
Which axes and units are used?
The input is a three-word text address. WGS 84 output defaults to latitude then longitude in decimal degrees.
How are precision and datum handled?
The converter returns the centre of the addressed 3 metre square as its representative coordinate.
Where can I use this coordinate system?
what3words coverage is worldwide. Conversion requires a valid API key.
What should I check?
- Include all three words and the separating full stops.
- Treat the returned coordinate as the centre of a 3 metre square.
- Use an API key whose plan and quota allow address-to-coordinate conversion.
Which coordinate is returned for an address?
The WGS 84 coordinate is the centre of the addressed 3 metre square.
Does a what3words address identify an exact point?
No. It identifies a 3 metre square, so this conversion returns the square's centre.
