Ever been stuck in the middle of nowhere trying to tell a friend exactly where you are, but "near the big oak tree" just isn't cutting it? Or maybe you're trying to plot a precise location for a drone flight or a hiking map. Knowing how to find out the coordinates of a place is one of those digital survival skills that feels nerdy until you actually need it. Then, it's a lifesaver.
Coordinates are basically the DNA of a location. They don't change because a shop closed down or a street sign fell over. We're talking about latitude and longitude—the invisible grid that wraps around the Earth. Latitude measures how far north or south you are from the Equator. Longitude measures east or west of the Prime Meridian in Greenwich, England. It sounds academic, but in practice, it's just two strings of numbers that tell a satellite exactly where you’re standing.
The Google Maps Trick Most People Miss
Most of us use Google Maps for directions to the nearest taco bell. But if you want to find out the coordinates of a place, the interface is actually built to give them to you instantly if you know where to click.
On a desktop, it’s stupidly easy. You just right-click any spot on the map. A little menu pops up. Right at the top of that menu, you’ll see a string of numbers like 40.7128, -74.0060. Those are your decimal degrees. If you click those numbers, Google automatically copies them to your clipboard. No highlighting, no ctrl+C, just click and go.
Mobile is a bit different. You can't right-click a touchscreen, obviously. Instead, you drop a pin. Long-press on the screen until that red marker appears. Once the pin is dropped, look at the search bar or pull up the location details from the bottom. The coordinates are usually tucked away right there. Sometimes they’re buried under a "plus code," which is Google’s own proprietary location system, but keep scrolling. The raw numbers are always there.
Understanding the "Why" Behind the Numbers
Why do some coordinates look like 40° 42' 46.02" N while others look like 40.712782?
It’s just different ways of saying the same thing. The first one is DMS (Degrees, Minutes, Seconds). It’s the old-school maritime way of doing things. Think of it like hours, minutes, and seconds on a clock. The second one is Decimal Degrees (DD). Computers love DD because it’s easier to calculate. If you’re plugging data into a GPS unit or a piece of software, you almost always want Decimal Degrees.
Accuracy matters here. A single decimal point can be the difference between standing in your kitchen and standing in your neighbor's pool.
- Four decimal places get you within about 11 meters.
- Five decimal places get you within 1.1 meters.
- Six decimal places? Now you're talking about 0.11 meters. That’s roughly the size of a grapefruit.
If you see a coordinate with ten decimal places, honestly, it’s overkill. Unless you're a surveyor or trying to land a rover on Mars, six is your magic number.
Beyond Google: Using What You Already Own
You don’t actually need an internet connection to find your coordinates if you have a modern smartphone. Your phone has a dedicated GPS chip. It doesn't need cell service to hear the satellites whispering from space.

On an iPhone, the Compass app is your best friend. Most people shove it into a "Utility" folder and forget it exists. Open it up. Assuming you've given it permission to see your location, your current latitude and longitude are displayed right at the bottom of the screen. It’s clean, it’s fast, and it works when you have zero bars of LTE in the woods.
Android users usually have to rely on Google Maps or a dedicated "GPS Status" app. But here’s a pro tip: if you’re using an Android device, you can often find your coordinates by opening the Camera app. If "Save Location" is turned on in your settings, every photo you take embeds those coordinates into the metadata (EXIF data). You can take a photo of the ground, check the "Details" of that photo in your gallery, and boom—there are your coordinates.
Apple Maps and the Privacy Factor
Apple handles things a little differently. If you’re an iOS devotee, you find out the coordinates of a place by tapping on the "My Location" blue dot or dropping a pin. You then have to swipe up on the info card. Apple doesn't make them as prominent as Google does, likely because they want to keep the interface "clean," but they are there.
Interestingly, Apple often formats location data using the Degrees, Minutes, Seconds format by default. If you need decimal degrees for a specific app, you might have to use a converter tool online. There are plenty of free ones like GPS-Coordinates.net or Boulter’s Converter.
Why Your Coordinates Might Be "Wrong"
Sometimes you'll get coordinates that seem slightly off. Maybe by 15 or 20 feet. This usually happens because of something called "signal bounce" or "multipath interference."
If you’re standing in a "urban canyon"—basically a street with really tall buildings on both sides—the GPS signals bounce off the glass and steel before hitting your phone. This delay tricks the phone into thinking you’re further away than you are. To get the most accurate reading, you need a clear view of the sky. Trees can even mess with it a bit if the canopy is thick enough.
Also, make sure your phone isn't in "Battery Saver" mode. To save juice, phones will often stop polling the GPS satellites as frequently or rely on lower-accuracy Wi-Fi positioning instead. If you need precision, turn off the power saving for a minute.

Geocaching and the Fun Side of Lat/Long
If you really want to master finding coordinates, look into Geocaching. It’s basically a global treasure hunt. People hide small containers and post the coordinates online. You use your phone or a handheld GPS to find them. It’s the ultimate practical application of this technology. You'll quickly learn that a coordinate is just a starting point; the real world has terrain, fences, and "No Trespassing" signs that the numbers don't tell you about.
How Pros Do It: What is WGS84?
If you ever find yourself in a deep conversation with a cartographer (it happens!), they might ask what "datum" you’re using.
Basically, the Earth isn't a perfect sphere. It's a lumpy, squashed potato. A "datum" is a mathematical model of that potato. Most of the world—and nearly every digital map like Google or Apple—uses a system called WGS84 (World Geodetic System 1984).
If you're looking at old paper maps, they might use NAD27 (North American Datum 1927). If you mix these up, your coordinates could be off by hundreds of feet. For 99% of people reading this, just stick to WGS84. It’s what your phone uses by default.
Getting Coordinates Without a Map
What if you have an address but no map? You can use a process called "Geocoding."
There are websites where you type in "1600 Pennsylvania Avenue, Washington, DC" and it spits back 38.8977° N, 77.0365° W. This is incredibly useful for developers or people managing large lists of addresses for a business. Tools like the Census.gov Geocoder are free and authoritative for US addresses.
Reverse geocoding is the opposite: you have the numbers, and you want the address. Google Maps handles this automatically. If you paste 48.8584, 2.2945 into the search bar, it’s going to show you the Eiffel Tower.
Actionable Steps for Precision
Finding coordinates isn't just about looking at a screen. It's about ensuring the data you're getting is actually useful for your specific goal.

Verify your format. Before you send coordinates to someone, ask what they need. If they’re using a handheld Garmin from 2005, they probably need DMS. If they're a tech-savvy hiker using the AllTrails app, Decimal Degrees are the way to go.
Check your "Locational Accuracy" settings. On both iPhone and Android, there is a setting called "Precise Location." If this is toggled off for your browser or map app, the coordinates you see will be a "fuzzy" estimate based on your nearest cell tower. For real coordinates, this must be turned on.
Use a dedicated GPS app for high-stakes tasks. If you're marking the boundary of a property or recording a scientific sample site, don't just rely on a quick tap in Google Maps. Use an app like "GPS Status & Toolbox" (Android) or "Commander Compass Go" (iOS). These apps show you exactly how many satellites your phone is currently "talking" to. The more satellites (aim for 12+), the better your data.
Standardize your notation. When writing them down, always put Latitude first, then Longitude. Remember that in the Western and Southern hemispheres, one of those numbers will be negative. In the US, your longitude is always a negative number (e.g., -122.4194 for San Francisco). Forget that little minus sign, and you’ve just placed your location in the middle of China.
Test before you travel. If you've found the coordinates for a remote trailhead, paste them back into a different map app to see if the pin drops in the same spot. It’s a 10-second double-check that prevents a three-hour wrong turn.
Coordinates are the ultimate universal language. They don't care what language you speak or what map you're holding. Once you know how to find them, the whole world becomes searchable in a way that street addresses can't touch.
