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 City of London

The DMS coordinates are: 51°30'46'' N 0°5'30.6'' W. Calculations are easier by using the decimal format, hence:

LatO = 51.5127907°

LngO = -0.09184°

Step 2: Calculate the latitude

LatA = - LatO = -51.5127907°

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

Step 3: Calculate the longitude

LngA = LngO ± 180° = -0.09184 + 180° = 179.90816°

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 substract 180° for the same reason.


Result

The antipode of City of London is located on coordinates (LatA, LngA) = (-51.5127907, 179.90816), or in DMS format: 51°30'46'' S 179°54'29.4'' E.
