You’re standing in the middle of a trail with no trailhead in sight. Or maybe you're trying to tell a delivery driver exactly which side of the massive apartment complex has the unlocked gate. Standard addresses fail us constantly. That’s why latitude and longitude coordinates Google Maps users rely on aren’t just for sailors or geography nerds anymore; they are the literal backbone of how we navigate a world that doesn't always have a street name.
Honestly, most of us just type "pizza near me" and call it a day. But if you’ve ever tried to mark a specific fishing spot or find a rural entrance in the desert, you know that a "pin" is only as good as the numbers behind it. These numbers—those long strings of decimals—represent your exact spot on the giant spinning rock we call Earth.
Why the Numbers Actually Matter
Google Maps has basically democratized surveying. Back in the day, you needed a sextant or an expensive handheld GPS unit to find your position. Now? You just long-press on a screen.
The system uses the WGS84 (World Geodetic System 1984) datum. It’s the standard used by the Global Positioning System. When you look at latitude and longitude coordinates Google Maps displays, the first number is the latitude. It tells you how far north or south you are from the Equator. The second is the longitude, measuring your distance east or west of the Prime Meridian in Greenwich, England.
It's a grid. Simple as that.
How to Grab Those Coordinates on Your Phone
Most people fumble with this. They drop a pin and then can't find the numbers. If you're on an iPhone or Android, the process is slightly different but follows the same logic.
First, open the app. Don't search for an address. Instead, find the physical spot on the map where you want the data. Long-press on the screen. A red pin will drop.
On Android, the coordinates usually pop right into the search bar at the top of the screen the moment that pin hits the ground. It's incredibly convenient. On iOS, you usually have to tap the "Dropped Pin" label at the bottom and scroll down a bit to see the decimal degrees.
What's cool is that you can tap those numbers to copy them to your clipboard. No more trying to memorize $34.0522$ and $-118.2437$ while switching between apps.

Doing it on a Desktop
Sometimes you're planning a trip from your office chair. This is actually easier.
Right-click anywhere on the map.
Seriously, that's it. A little menu pops up, and the very first thing at the top of that menu is a pair of decimal numbers. If you left-click those numbers, Google Maps automatically copies them for you. It’s one of those "hidden in plain sight" features that makes you wonder why you ever struggled with typing them out manually.
The Difference Between Formats
This is where people get tripped up and think the app is broken. Geography uses a few different languages to say the same thing.
- Decimal Degrees (DD): This is what Google Maps defaults to. Example: $41.40338$, $2.17403$. It’s clean. It’s what computers like.
- Degrees, Minutes, and Seconds (DMS): The old-school way. $41^\circ 24' 12.2'' N$ $2^\circ 10' 26.5'' E$.
- Degrees and Decimal Minutes (DMM): $41 24.2028, 2 10.4418$.
If you have coordinates in the DMS format from an old paper map or a hiking guide, you can just paste them directly into the Google Maps search bar. It’s smart enough to translate. Just make sure you use the degree symbol or at least leave spaces where they belong so the algorithm doesn't have a stroke.
Why Your Coordinates Might Be "Wrong"
Accuracy isn't always perfect. You’ve probably noticed the blue dot on your phone sometimes has a wide light-blue circle around it. That’s your "margin of error."
GPS signals come from satellites. If you are under a thick tree canopy, standing next to a skyscraper in Chicago, or inside a basement, your latitude and longitude coordinates Google Maps provides might be off by 20 or 30 meters. In "urban canyons," the signal bounces off glass and steel, leading to "multipath errors." This is why your Uber driver sometimes thinks you're on the street behind the one you're actually standing on.
To get the best accuracy, turn on Wi-Fi. Even if you aren't connected to a network, your phone uses the "MAC addresses" of nearby routers to triangulate your position. It’s a bit creepy, but it makes that blue dot much smaller.

Plus Codes: The Coordinate Shortcut
Google realized that $37.4221, -122.0841$ is a nightmare to communicate over the phone. So they invented Plus Codes.
If you look at the info panel for a dropped pin, you’ll often see a weird string like "849VCWC8+R9." That is a Digital Address. It’s basically a short-hand version of coordinates. If you're in a place with no house numbers—like a rural village in India or a specific spot on a beach—a Plus Code works exactly like a street address. You can type it into the search bar, and it takes you to the exact 10x10 meter square.
Practical Uses You Didn't Think Of
Geocaching is the obvious one. It’s a global scavenger hunt where people hide containers and post the coordinates online.
But think about safety. If your car breaks down on a rural road with no landmarks, telling a dispatcher your coordinates is much faster than saying "I'm near a big oak tree past the red barn."
Photographers use them to return to the exact spot for a "golden hour" shot. Real estate developers use them to mark the corners of an empty lot before the foundation is poured. It’s the ultimate "you are here" marker.
A Note on Privacy
Every time you share a location or search for coordinates, you are leaving a digital breadcrumb. Google Timeline (now often stored on-device) keeps track of these. If you are looking up coordinates for sensitive reasons, it's worth checking your location history settings. You can delete specific entries or turn the whole thing off if you're feeling particularly "off the grid."

How to Input Coordinates Correctly
If someone sends you a set of numbers, don't just wing it. There are rules.
- Latitude goes first. 2. Use dots, not commas, for decimals. $41.40338$ is right. $41,40338$ will confuse it.
- Check your signs. Latitude is positive for North and negative for South. Longitude is positive for East and negative for West (most of the US will have a negative longitude).
If you're in the US and your map suddenly shows you the middle of the Indian Ocean, you probably forgot the minus sign in front of your longitude. It happens to the best of us.
Beyond the Basics: Elevation
One thing Google Maps is surprisingly cagey about is altitude. While you can get your horizontal position perfectly, the app doesn't always make it easy to see how high up you are. To get elevation data alongside your latitude and longitude coordinates Google Maps doesn't always show it in the basic view. You usually have to toggle the "Terrain" layer to see contour lines, or use a specialized tool like Google Earth if you need to know exactly how many feet you are above sea level.
Actionable Steps for Your Next Trip
Stop relying on "near the park." It's vague.
Next time you find a perfect camping spot or a great "secret" parking entrance, do this:
- Drop a pin immediately while standing there.
- Save it to a "private list" in Google Maps (Label it something like "Hidden Spots").
- Share the coordinates via text to a friend so they have it in their chat history.
- Download the offline map of that area. Coordinates still work even when you have zero bars of cell service, as long as your GPS chip can see the sky.
Mastering these coordinates turns the map from a simple "A to B" tool into a precision instrument. It takes the guesswork out of meeting up and ensures that "middle of nowhere" is a place you can actually find again.
Next Steps:
To put this into practice, open Google Maps on your computer right now. Right-click on your favorite local landmark and look at those numbers. Copy them, then paste them into the search bar to see how the app centers back onto that exact spot. Once you're comfortable with the right-click method, try long-pressing on your phone to drop a "Temporary Pin" and practice sharing that exact location with a contact. It’s a small skill that becomes a lifesaver the moment you step off the sidewalk.
