Where would you end up if you dug straight through the Earth? Search a place, type coordinates or click the map to find its antipode, the exact opposite point on the globe, shown side by side with land or ocean and the nearest big city.

Search a place such as a city name, or type coordinates like 40.42, -3.70, then press Find antipode.
Or click the left map to drop your point anywhere on Earth.
Read the antipode on the right: its coordinates, whether it is land or water, and the nearest big city.
Click the right map if you want to pick the antipode and see where its opposite lies.
Copy the coordinates or open the antipode in OpenStreetMap to explore the area.
The antipode formula
Two points are antipodal when the straight line between them passes through Earth's center. On a latitude/longitude grid that means:
Antipode latitude = −latitude (north becomes south by the same amount).
Antipode longitude = longitude + 180° if the longitude is negative (west), or longitude − 180° if it is positive (east).
Example: New York (40.71° N, 74.01° W) → 40.71° S, 105.99° E, which is in the Indian Ocean southwest of Australia. The calculation treats Earth as a sphere for the formula, which is exact for latitude/longitude on the standard ellipsoid as well, because flipping both coordinates is symmetric about the center.

Fun facts about the other side of the world
Most land is opposite water. Because the continents are bunched in the Northern Hemisphere and the Southern Hemisphere is mostly ocean, a random land point usually has an ocean antipode.
Opposite seasons and times. Antipodes always have opposite seasons and a 12-hour time difference in solar time: when it is noon in one place it is midnight at the other.
The same sky, upside down. Stars overhead at one antipode are directly under the feet of someone at the other.
"The Antipodes" is an old British nickname for Australia and New Zealand, which lie roughly opposite the British Isles (though the true antipode of Britain is in the ocean southeast of New Zealand).
Frequently asked questions
How do you calculate an antipode?
Flip the sign of the latitude and shift the longitude by 180 degrees. For example 40.42° N, 3.70° W (Madrid) becomes 40.42° S, 176.30° E, which is on New Zealand's North Island. If the shifted longitude goes past 180°, subtract 360°.
If I dig a hole through the Earth, where do I come out?
For most places in North America, Europe and Africa you would come out in the Indian or Pacific Ocean, because land covers less than a third of the planet and most land is in the Northern Hemisphere. People in Spain, Portugal, China, Argentina, Chile and a few other places would land on solid ground.
How much land has land on the opposite side?
Only a small part. Roughly 15% of land area is antipodal to other land, which is about 4% of Earth's whole surface. The largest land-to-land overlaps are South America with East and Southeast Asia, and the Iberian Peninsula with New Zealand.
What is the antipode of the United States?
Almost all of the contiguous United States is antipodal to the southern Indian Ocean, southwest of Australia. Hawaii's antipode lies in southern Africa, in and around Botswana, and parts of northern Alaska are opposite Antarctica.
How far away is the antipode?
Any antipode is as far away as you can get on Earth: about 20,015 km (12,437 miles) along the surface, half of Earth's circumference, and about 12,742 km (7,918 miles) through the center along Earth's diameter.
Is the land or water result exact?
It uses Natural Earth country outlines at 1:110 million scale, which leave out small islands and simplify coastlines. Points within a few kilometers of a coast, or on small islands, may be shown on the wrong side. If the detailed shapes cannot load, a simplified built-in coastline is used.
