How does this calculator work?
The antipode of (lat, lon) is (−lat, lon ± 180°). Negate the latitude to swap hemispheres and shift the longitude by 180°, wrapping to stay within ±180°. The result is the point reached by a straight path through Earth's centre. More than 96% of land antipodes fall in ocean.
Formula
How this is calculated
The antipode of a point is the location diametrically opposite it through the Earth's centre — where you would emerge if you could drill a straight tunnel through the planet. Because Earth is a sphere with 360° of longitude and 180° of latitude range, the rule is elegantly simple: negate the latitude (turning North into South and vice versa, the same number of degrees) and shift the longitude by exactly 180°, wrapping the result to stay within the ±180° range.
Latitude flips sign directly: 51.5° N becomes 51.5° S. Longitude shifts by ±180° depending on which side of the prime meridian keeps the result in bounds: −74° W becomes +106° E, and +139° E becomes −41° W. The result is displayed in both decimal degrees (the format most mapping apps use) and degrees-minutes-seconds (DMS, the traditional survey format).
Most land areas have their antipode in ocean — over 71% of Earth is water, so the probability that a random continental point maps to another continental point is only about 3–4%. Notable land-to-land antipodal pairs include the Iberian Peninsula (Spain/Portugal) and New Zealand, and parts of Argentina opposite parts of China.
Frequently asked questions
An antipode is the point on Earth's surface directly opposite another, connected through the planet's centre. It is found by negating the latitude and shifting the longitude by 180°.
Almost always yes. Over 71% of Earth is ocean, and fewer than 4% of land points have another land area as their direct antipode. Most continental locations map to a point somewhere in the Pacific, Atlantic or Indian Ocean.
South latitudes are negative (−33.87 = 33.87° S), north are positive. West longitudes are negative (−74.01 = 74.01° W), east are positive. Most map apps and GPS devices display coordinates in decimal degrees.
