The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
Step 1: Obtain the geographic coordinates of Saint Helier
The DMS coordinates are: 49°11'16.9'' N 2°6'17.7'' W.
Calculations are easier by using the decimal format, hence:
LatO = 49.18804°
LngO = -2.10491°
Step 2: Calculate the latitude
LatA = - LatO = -49.18804°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -2.10491 + 180° = 177.89509°
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.
Result:
The antipode of Saint Helier is located on coordinates: (LatA, LngA) = (-49.18804, 177.89509)
In DMS format: 49°11'16.9'' N 2°6'17.7'' W.
