Antipode Calculator
Find the antipodal point of any location on Earth. Enter latitude and longitude to calculate the exact opposite point on the globe with coordinates and degree formatting.
About This Calculator
The Antipode Calculator helps you find the exact opposite point of any location on Earth. If you were to dig a straight tunnel through the center of the planet, the point where you would emerge is the antipode. This free online tool is perfect for geography enthusiasts, students, teachers, and anyone curious about Earth's geometry.
To calculate the antipode, the formula is straightforward: negate the latitude (e.g., 40°N becomes 40°S), and adjust the longitude by adding 180° if it is 0 or negative, or subtracting 180° if it is positive. The result gives you the precise antipodal coordinates in degree notation.
Regional Reference Coordinates
India: New Delhi at 28.61°N, 77.23°E. Its antipode is 28.61°S, 102.77°W in the Pacific Ocean.
United States: New York City at 40.71°N, 74.01°W. Its antipode is 40.71°S, 105.99°E in the Indian Ocean.
United Kingdom: London at 51.51°N, 0.13°W. Its antipode is 51.51°S, 179.87°E near New Zealand's Antipodes Islands.
Only about 15% of Earth's land has a land antipode because oceans cover over 70% of the planet's surface. The Antipodes Islands of New Zealand are named after this concept — they are almost antipodal to London.
Frequently Asked Questions
What is an antipode?
An antipode is the diametrically opposite point of a given location on a sphere. If you dug a straight tunnel through the center of the Earth, you would emerge at the antipode of your starting point.
How do you calculate the antipode of a location?
To calculate the antipode, simply negate the latitude (e.g., 40°N becomes 40°S), and adjust the longitude by adding or subtracting 180° (e.g., 74°W or -74 becomes 106°E or +106). If the original longitude is 0 or negative, add 180; if positive, subtract 180.
What is the antipode of New York City?
The antipode of New York City (40.71°N, 74.01°W) is approximately 40.71°S, 105.99°E, which lies in the Indian Ocean southwest of Australia.
What is the antipode of London?
The antipode of London (51.51°N, 0.13°W) is approximately 51.51°S, 179.87°E, which lies in the Pacific Ocean near the Antipodes Islands of New Zealand.
What is the antipode of Delhi?
The antipode of New Delhi (28.61°N, 77.23°E) is approximately 28.61°S, 102.77°W, which lies in the southeastern Pacific Ocean west of Chile.
Is there land at every antipode?
No, only about 15% of land on Earth has a land antipode. Since oceans cover over 70% of the planet, most antipodal points lie in the ocean, particularly the Pacific Ocean.
What is the Earth Sandwich?
In 2020, two people in New Zealand and Spain placed bread slices at exact antipodal coordinates, creating an 'Earth Sandwich.' This demonstrated the concept of antipodes in a fun, viral way.
How do I find my exact antipode?
Find your current coordinates using Google Maps (right-click on the map), enter the latitude and longitude into this antipode calculator, and it will instantly compute the exact opposite point on the globe.
