Straight-line (great circle) distance

The distance from Si Racha to Hat Yai is about 687 km (427 miles) as the crow flies, or 371 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 0.9 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.
