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 Avarua
The DMS coordinates are: 21°12'27'' S 159°46'31.7'' W.
Calculations are easier by using the decimal format, hence:
LatO = -21.2075°
LngO = -159.77546°
Step 2: Calculate the latitude
LatA = - LatO = 21.2075°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -159.77546 + 180° = 20.22454°
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 Avarua is located on coordinates: (LatA, LngA) = (21.2075, 20.22454)
In DMS format: 21°12'27'' S 159°46'31.7'' W.
