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 Johnston
The DMS coordinates are: 41°49'18.7'' N 71°30'24.3'' W.
Calculations are easier by using the decimal format, hence:
LatO = 41.82186°
LngO = -71.50675°
Step 2: Calculate the latitude
LatA = - LatO = -41.82186°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -71.50675 + 180° = 108.49325°
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 Johnston is located on coordinates: (LatA, LngA) = (-41.82186, 108.49325)
In DMS format: 41°49'18.7'' N 71°30'24.3'' W.
