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 Onchan
The DMS coordinates are: 54°10'23.8'' N 4°27'11.7'' W.
Calculations are easier by using the decimal format, hence:
LatO = 54.17329°
LngO = -4.45324°
Step 2: Calculate the latitude
LatA = - LatO = -54.17329°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -4.45324 + 180° = 175.54676°
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 Onchan is located on coordinates: (LatA, LngA) = (-54.17329, 175.54676)
In DMS format: 54°10'23.8'' N 4°27'11.7'' W.
