Straight-line (great circle) distance
The distance from Hanoi to Zhongshan is about 796 km (495 miles) as the crow flies, or 430 nautical miles.
This is the great-circle distance — the shortest path over the surface of the Earth, computed with the haversine formula from the coordinates of both cities. Road or rail distance is always longer, and the gap widens with every mountain range or coastline in between.
Putting the number to use
- At a cruising speed near 800 km/h the airborne time is about 1.0 hours; add 30-45 minutes for taxi, climb and descent.
- Time zone difference changes the arrival time on your ticket far more than the flying time does.
- For shipping, use road or sea distance instead — great-circle figures understate real routes.
