Distance Between Cities
Formula
Haversine: d = 2R x arcsin(sqrt(sin²((lat2-lat1)/2) + cos(lat1) x cos(lat2) x sin²((lon2-lon1)/2)))
Frequently Asked Questions
How is the distance calculated?
The calculator uses the Haversine formula to compute the great-circle distance between two points on Earth, which is the shortest distance over the Earth's surface.
Is straight-line distance the same as flight distance?
Actual flight distances are typically 5-15% longer than straight-line (great-circle) distances due to air traffic routes, wind patterns, and restricted airspace.
How is flight time estimated?
Flight time is estimated based on an average cruising speed of 550 mph (885 km/h). Actual times vary based on aircraft type, wind conditions, and routing.
