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 Rongelap
The DMS coordinates are: 11°9'48.6'' N 166°53'38.7'' E .
Calculations are easier by using the decimal format, hence:
LatO = 11.16351°
LngO = 166.89408°
Step 2: Calculate the latitude
LatA = - LatO = -11.16351°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 166.89408 - 180° = -13.10592°
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 Rongelap is located on coordinates: (LatA, LngA) = (-11.16351, -13.10592)
In DMS format: 11°9'48.6'' N 166°53'38.7'' E .
