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 Francisco
The DMS coordinates are: 20°43'0'' S 64°42'0'' W.
Calculations are easier by using the decimal format, hence:
LatO = -20.71667°
LngO = -64.7°
Step 2: Calculate the latitude
LatA = - LatO = 20.71667°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -64.7 + 180° = 115.3°
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 Francisco is located on coordinates: (LatA, LngA) = (20.71667, 115.3)
In DMS format: 20°43'0'' S 64°42'0'' W.
