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 Viengthong

The DMS coordinates are: 20°19'40.5'' N 103°24'30.8'' E .

Calculations are easier by using the decimal format, hence:

LatO = 20.32792°

LngO = 103.40856°

Step 2: Calculate the latitude

LatA = - LatO = -20.32792°

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

Step 3: Calculate the longitude

LngA = LngO ± 180° = 103.40856 - 180° = -76.59144°

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 Viengthong is located on coordinates: (LatA, LngA) = (-20.32792, -76.59144)

In DMS format: 20°19'40.5'' N 103°24'30.8'' E .
