Short answer
How many decimal places you need
| Decimals | Latitude step | Longitude step at 39.7° N |
|---|---|---|
| 1 | 11,103 m | 8,572 m |
| 2 | 1,110 m | 857 m |
| 3 | 111 m | 86 m |
| 4 | 11 m | 8.57 m |
| 5 | 1.11 m | 0.86 m |
| 6 | 0.11 m | 0.09 m |
How to use it
- Click the map where you want coordinates. Zoom in first for precision.
- Or search a place, tap Use GPS, or paste coordinates in any common format into Paste coordinates.
- The card lists the point as decimal degrees, degrees-minutes-seconds, degrees and decimal minutes, UTM, a nine-character geohash, and a plus code.
- Click a value to copy it to your clipboard.
The six formats
DD is decimal degrees, the format most software wants. DMS splits each degree into 60 minutes and each minute into 60 seconds. DMM keeps degrees and decimal minutes, the usual format on marine and aviation GPS units.
UTM gives meters east and north within one of 60 zones. Geohash encodes the point as a short string where each extra character narrows the cell. Plus codes are Google's open location codes, which work as addresses where streets have no numbers.
Precision you can trust
Six decimal places in DD is about 11 centimeters of latitude, much finer than a phone's GPS, which is usually good to a few meters in open sky. A click on a web map is only as precise as the zoom level. Zoom in before clicking if you need a point on a specific building.
The decimal places guide covers how many digits to keep for different jobs.
Datum
All values are on WGS84, the datum used by GPS and every major web map. Older US paper maps may use NAD27, which can put the same spot tens of meters away or more. If numbers from an old map do not line up, the datum is the first thing to check.
Sharing a location
To send someone a spot, copy the decimal degrees and paste them into a message. Most map apps turn "39.739, -104.985" into a tappable location. For a spoken or written address where streets have no numbers, a plus code is shorter and easier to read aloud.
Questions people ask
Which format should I send someone?
Decimal degrees with latitude first, such as 39.739, -104.985. Every map app reads it.
Is GPS on a phone accurate enough?
Usually to a few meters outdoors. Indoors and between tall buildings it can be much worse.
What datum are the coordinates on?
WGS84.
