sci.geodetic-distance-vincenty Calculator
Calculates the geodesic distance between two points on the WGS84 ellipsoid using the Vincenty inverse formula with millimetre-level accuracy. Vincenty converges in 3–5 iterations for most coordinate pairs — it fails for nearly antipodal points where Karney's algorithm should be used instead.
Inputs
Lat1 Deg
Reference formula or conversion factor shown for context.
Lon1 Deg

Results
great-circle distance (km)
The computed distance or separation.
distance (nautical miles)
The computed distance or separation.
initial bearing (degrees)
The magnitude or severity on the applicable scale.
Haversine formula (spherical Earth)
The specific form or variant of the result.
WGS84 ellipsoid error
The difference between the computed result and the exact or true value — a measure of approximation accuracy.
