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 ‘Ohonua
The DMS coordinates are: 21°19'60'' S 174°56'60'' W.
Calculations are easier by using the decimal format, hence:
LatO = -21.33333°
LngO = -174.95°
Step 2: Calculate the latitude
LatA = - LatO = 21.33333°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -174.95 + 180° = 5.05°
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.
The antipode of ‘Ohonua is located on coordinates: (LatA, LngA) = (21.33333, 5.05)
In DMS format: 21°19'60'' S 174°56'60'' W.
