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 Callao
The DMS coordinates are: 12°3'5.8'' S 77°8'4.3'' W.
Calculations are easier by using the decimal format, hence:
LatO = -12.05162°
LngO = -77.13452°
Step 2: Calculate the latitude
LatA = - LatO = 12.05162°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -77.13452 + 180° = 102.86548°
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 Callao is located on coordinates: (LatA, LngA) = (12.05162, 102.86548)
In DMS format: 12°3'5.8'' S 77°8'4.3'' W.
