How to calculate the antipodal point?

The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:

  • LatO: Latitude at the origin point.
  • LngO: Longitude at the origin point.
  • LatA: Latitude at the antipodal point.
  • LngA: Longitude at the antipodal point.

Step 1: Obtain the geographic coordinates of Houaïlou

The DMS coordinates are: 21°16'60'' S 165°37'0'' E .

Calculations are easier by using the decimal format, hence:

LatO = -21.28333°

LngO = 165.61667°

Step 2: Calculate the latitude

LatA = - LatO = 21.28333°

Since the latitude is negative (south direction), the antipode must be positive (north direction).

Step 3: Calculate the longitude

LngA = LngO ± 180° = 165.61667 - 180° = -14.38333°

Since the longitude is positive, we subtract 180° to ensure the final value lies between (-180, 180). If it were the other way around, we would sum 180° for the same reason.


The antipode of Houaïlou is located on coordinates: (LatA, LngA) = (21.28333, -14.38333)

In DMS format: 21°16'60'' S 165°37'0'' E .
