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 San Juan
The DMS coordinates are: 16°33'44.4'' N 88°30'55'' W.
Calculations are easier by using the decimal format, hence:
LatO = 16.56232°
LngO = -88.51528°
Step 2: Calculate the latitude
LatA = - LatO = -16.56232°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -88.51528 + 180° = 91.48472°
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 San Juan is located on coordinates: (LatA, LngA) = (-16.56232, 91.48472)
In DMS format: 16°33'44.4'' N 88°30'55'' W.
