What your result means
- Feet (large) and meters
- How high the ground at your position is above the sea-level reference (NAVD 88 in the contiguous US). A minus sign means below it.
- Place and coordinates
- Where the tool measured: a place name and the exact latitude and longitude. If the place is wrong, your device located you poorly; try again outdoors or search an address.
- Accuracy line
- How close the value should be, from the published accuracy of the elevation data and your device's location accuracy. "How accurate is this?" shows each part.
- Data sources
- The dataset that answered: USGS 3DEP in the US, Terrain Tiles elsewhere, with required credits.
- Life at this elevation
- The temperature water boils at, air pressure and oxygen per breath compared with sea level, each linked to a calculator filled in with your elevation.
What each elevation means
Standard-atmosphere figures for common elevations, with the thresholds USDA and the CDC use.
| Elevation | Water boils at | Air pressure | Oxygen per breath | Note |
|---|---|---|---|---|
| 0 ft (0 m) | 212.0 °F | 29.92 inHg | 100% | Sea level |
| 1,000 ft (305 m) | 210.2 °F | 28.86 inHg | 96% | |
| 2,000 ft (610 m) | 208.4 °F | 27.82 inHg | 93% | |
| 3,000 ft (914 m) | 206.5 °F | 26.82 inHg | 90% | USDA: high altitude for cooking starts here |
| 5,280 ft (1,609 m) | 202.4 °F | 24.64 inHg | 82% | One mile |
| 8,000 ft (2,438 m) | 197.4 °F | 22.22 inHg | 74% | CDC: altitude illness risk when sleeping at about this height or higher |

Worked examples
At the Colorado State Capitol
A point at the Capitol building in Denver (39.73924, −104.98486) returns 5,276 ft (1,608 m) from USGS 3DEP, a few feet short of a mile. At that elevation water boils at about 202.4 °F and each breath holds about 82% of the oxygen it would at sea level.
Mount Elbert: map data vs. a survey mark
Colorado's highest point has an official surveyed height of 14,440 ft (NOAA National Geodetic Survey datasheet KL0637). The highest USGS 3DEP value near the summit is 14,432 ft, 8 ft lower. Elevation models describe the ground in small cells, so sharp summits read slightly low; for named peaks, use the surveyed figure on the peak page.
Below sea level in Death Valley
Badwater Basin is 282 ft below sea level, the lowest point in the US (USGS). The result card shows a negative number and says "below sea level"; water there boils slightly above 212 °F.
How it works
- Tap Find my elevation and allow location access when your browser asks. Without it, search a US street address, type coordinates or click the map.
- Our server looks up the ground elevation at those coordinates: from the USGS Elevation Point Query Service (3D Elevation Program) in the US, and from Terrain Tiles elsewhere.
- The result shows feet first and meters below, with the data's published accuracy and your device's location accuracy.
- Every result has its own link (the coordinates are in the address bar), so you can share or bookmark it.
Accuracy and limitations
- Elevation data: USGS reports an overall vertical accuracy (RMSE) of about 0.53 m (1.7 ft) for 3DEP. Outside the US, accuracy depends on the source data for that country.
- Your position: on a slope, a small sideways location error changes the elevation. Indoors GPS is less precise; try near a window or outdoors.
- Ground, not you: the value is bare earth. Floors, towers and aircraft are not included.
- Summits and cliffs: elevation models smooth sharp features, so peaks read a little low; surveyed heights are on our mountain pages.
- Reference surface: US values are above NAVD 88, not the raw height a GPS receiver calculates from its own model of the Earth.
Glossary
- Elevation:
- the height of the ground at a place above sea level. It does not change.
- Altitude:
- the height of something above sea level or the ground, such as a plane; it changes as it moves.
- NAVD 88:
- the surveyed reference surface for official US heights, standing in for mean sea level (NOAA).
- 3DEP:
- the USGS 3D Elevation Program, the national elevation dataset (USGS).

Frequently asked questions
How can I find the elevation of my location?
Tap "Find my elevation" and allow location access. The tool looks up the surveyed ground elevation at your position and shows it in feet and meters. Without location access, search an address, type coordinates or click the map.
Can Google Maps tell me my elevation?
Not as a number for your spot. The Terrain layer shows contour lines you can read roughly, but there is no elevation readout for a point. This tool gives the value directly, from USGS data in the US.
Can my phone tell my elevation?
Many compass and GPS apps show an altitude from the phone's GPS or barometer. GPS altitude is usually less precise than GPS position, and barometer readings drift with the weather. This tool uses your phone only to find where you are, then looks up the mapped ground elevation there.
Is 2,000 ft considered high altitude?
Not by the usual thresholds. USDA treats 3,000 ft and above as high altitude for cooking, and the CDC puts the risk of altitude illness at sleeping elevations of about 8,000 ft or higher. At 2,000 ft water boils at about 208 °F instead of 212 °F.
How accurate is my elevation?
In the United States the value comes from the USGS 3D Elevation Program, which USGS reports has an overall vertical accuracy (RMSE) of about 0.53 m (1.7 ft). The result also depends on how precisely your device located you; the card shows both under "How accurate is this?".
Why is this different from the altitude my phone shows?
A phone's GPS altitude is an estimate from satellite signals and is usually less precise vertically than horizontally, and GPS measures height from a different reference surface than sea level. This tool uses your position only to find where you are, then looks up the surveyed ground elevation at that point.
Why is my elevation negative?
A minus sign means the ground is below the sea-level reference (NAVD 88 in the contiguous US). Badwater Basin in Death Valley, at 282 ft below sea level, is the lowest point in the United States.
What is the elevation of my house?
Use elevation by address: search your street address, then click your roof or yard on the map for the ground at the house itself.
Is the elevation for the ground or for where I am standing?
For the ground at your position. If you are on an upper floor or in a plane, add your height above the ground yourself.
Does it work outside the United States?
Yes. Outside the US the elevation comes from Terrain Tiles, an open dataset that blends national and global elevation models. Accuracy varies by country; the result card shows the published figure for the data used at your spot when one exists.
What is the difference between elevation and altitude?
Elevation is the height of a point on the ground above sea level. Altitude is the height of something above sea level or the ground, such as a plane, and changes as it moves. This tool reports elevation.
Is my location saved?
Your coordinates are sent to our server to look up the elevation, and the result is stored by coordinates for up to 90 days so repeat lookups are fast. We do not store it with anything that identifies you. The lookup itself goes to the data providers listed under Sources.
