Enter your coordinates in decimal degrees here to calculate how accurate they are likely to be:

Lat: Long: [Datum is assumed to be WGS84]

The uncertainty of a given coordinate depends on the number of decimal places quoted as well as the latitude, because the physical size of a degree changes as you move further from the equator.

You can also use the Latitude/Longitude Entry Form to get the same results via the coordinate converter (for WGS84 Datum)
