Estimated Total Travel Time
7h 16m
Includes ~45 minutes for taxiing, takeoff, and landing procedures.
Mathematical Formula
d = 2r × arcsin(sqrt(sin²(Δlat/2) + cos(lat1) × cos(lat2) × sin²(Δlng/2)))
Overview & Explanation
Calculates precise direct geodesic line distance across the globe.
How It Works
- Utilizes spherical trigonometry (Haversine equation) on Earth radius r = 6,371 km.
Practical Applications
- Measuring distance between cities
- Aviation flight planning
