What3Words (W3W) is a geocoding system that uses three words separated by periods to identify any location on Earth with about 3 meters of resolution. Enter words individually here, or change the drop-down to automatic and enter all three with periods between them.

Example: Big Ben in London, UK

• gums.clubs.terms

Military Grid Reference System (MGRS) is split into 4 sections: grid zone band, grid zone identifier, easting, and northing. Enter each part here or use the automatic conversion to enter them all at once (with or without spaces).

Example: Big Ben in London, UK

• 30U XC 99567 09427

Universal Transverse Mercator (UTM) is split into 4 sections: zone number, zone letter, easting, and northing.

Example: Big Ben in London, UK

• 30 U 699567.54 5709427.56

Degree Decimal Minutes (DDM) is the standard format used by Geocaching and electronic navigation equipment. Format: (NS+-)DD MM.MMMM (WE+-)DDD MM.MMMM

Example: Big Ben in London, UK

• N51° 30.042 W000° 7.476

Decimal Degrees (DD) represents lat/lon as a floating point decimal. This tool calculates to 6 digits past the decimal. Format: (NS+-)DD.DDDDDD, (WE+-)DDD.DDDDDD

Example: Big Ben in London, UK

• 51.500700, -0.124600

Degrees, Minutes & Seconds (DMS) is typically used in nautical navigation. This tool gives decimal seconds up to thousands for accuracy. Format: (NS+-)DD MM SS.SS, (WE+-)DDD MM SS.SS

Example: Big Ben in London, UK

• N51° 30' 2.52" W0° 7' 28.56"

Plus Codes, also known as Open Location Code, identify any area on Earth — especially useful where addresses don't exist. This tool only supports the global version for converting.

Example: Big Ben in London, UK

• 9C3XGV2G+75J525

Reverse Wherigo (Waldmeister) is a wherigo that gives the distance to the final cache rather than coordinates. Solve using the three 6-digit codes.

Example: Big Ben in London, UK

• 015301 506204 068070

Geo3x3 (G3) is a WGS84 geocoding system that recursively divides the earth into 9 areas of 3x3. Begins with E or W; longer codes are higher accuracy. Up to 20 characters supported.

Example: Big Ben in London, UK

• W9633932282187272119

Geohash (GH) expresses a location as a short alphanumeric string. Up to 12 characters supported.

Example: Big Ben in London, UK

• gcpuvpmm2d79

GeoHex (GX) uses honeycomb geometry. Up to 20 characters supported.

Example: Big Ben in London, UK

• QE01666112473272870570

Reverse Wherigo day1976 is a wherigo that gives bearing rather than coordinates. Only 5 decimal places of accuracy. Solve using two 5-character/number codes.

Example: Big Ben in London, UK

• AP8JF A99WI

Natural Area Code (NAC), also known as Universal Address. A full 10-digit NAC is about one square meter.

Example: Big Ben in London, UK

• GZNMMH RKH34G

Mercator (XY), web mercator projection, used by web mapping applications. Split into easting (X) and northing (Y).

Example: Big Ben in London, UK

• X: -13870.40855284189,
  Y: 6710344.259782706

Maidenhead (MH), also known as QTH Locator, is used by amateur radio operators.

Example: Big Ben in London, UK

• IO91WM50BE10MH46

Mapcode (MC) uses 5 chars + period + 4 chars (and optional dash + extra chars for accuracy). This tool uses International format with a default of 3 extra accuracy characters.

Example: Big Ben in London, UK

• VHGQZ.SJHX-6W9

British National Grid (OSGB) covers Great Britain to ~1 meter accuracy. Up to 5 digits in easting and northing supported. Note: coordinates outside the British Grid will not return results.
