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 Grootfontein
The DMS coordinates are: 19°34'0'' S 18°7'0'' E .
Calculations are easier by using the decimal format, hence:
LatO = -19.56667°
LngO = 18.11667°
Step 2: Calculate the latitude
LatA = - LatO = 19.56667°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 18.11667 - 180° = -161.88333°
Since the longitude is positive, we subtract 180° to ensure the final value lies between (-180, 180). If it were the other way around, we would sum 180° for the same reason.
Result:
The antipode of Grootfontein is located on coordinates: (LatA, LngA) = (19.56667, -161.88333)
In DMS format: 19°34'0'' S 18°7'0'' E .
