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 Saint Sampson

The DMS coordinates are: 49°29'2'' N 2°31'24'' W.

Calculations are easier by using the decimal format, hence:

LatO = 49.48389°

LngO = -2.52333°

Step 2: Calculate the latitude

LatA = - LatO = -49.48389°

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

Step 3: Calculate the longitude

LngA = LngO ± 180° = -2.52333 + 180° = 177.47667°

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


The antipode of Saint Sampson is located on coordinates: (LatA, LngA) = (-49.48389, 177.47667)

In DMS format: 49°29'2'' N 2°31'24'' W.
