Get Elevation from Latitude and Longitude
Enter coordinates in decimal or degrees-minutes-seconds to get the elevation above sea level. Need many points? Use the bulk box below.

Standard-atmosphere estimates for this elevation. Weather changes the real values a little day to day.
- Oxygen per breath
- % of sea level
- Air is still 20.9% oxygen; there is just less air.
- Oxygen at altitude
Sources: pressure from the U.S. Standard Atmosphere, 1976 (NOAA, NASA, USAF); boiling point from the Antoine equation for water (Lange's Handbook of Chemistry). Methodology.
How it works
We read your coordinates, round them to 5 decimal places (about 1 m), and look up the ground elevation at that point: from the USGS 3D Elevation Program inside the US, and from Terrain Tiles elsewhere. Feet come first, with meters alongside, and each result shows the published accuracy of the data behind it.

Frequently asked questions
Which coordinate formats can I enter?
Decimal degrees (39.7392, -104.9903), degrees and decimal minutes (39 44.35 N, 104 59.42 W) and degrees, minutes and seconds (39°44'21"N 104°59'25"W). Latitude comes first unless you mark the longitude with E or W.
Which way round do latitude and longitude go?
Latitude (north–south, -90 to 90) first, then longitude (east–west, -180 to 180). West longitudes and south latitudes are negative in decimal form, so all of the contiguous US has negative longitudes.
How many points can I look up at once?
Up to 100 in the bulk box, one per line. Results appear in a table you can download as a CSV file.
Where does the elevation come from?
US points come from the USGS 3D Elevation Program; elsewhere from Terrain Tiles, an open blend of national and global elevation models. Each result names its source.
