Global Geodesic Flight Distance Calculator

Measure exact point-to-point air distance between geographic coordinates using geodesic haversine calculations.

Origin Latitude / Longitude

Destination Latitude / Longitude

Cruising Speed (km/h)

Flight Distance (Great Circle)

5,540 km (3,442 miles)

Estimated Total Travel Time

7h 16m

Includes ~45 minutes for taxiing, takeoff, and landing procedures.

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.

Utilizes spherical trigonometry (Haversine equation) on Earth radius r = 6,371 km.

Compute direct air distance NYC to LHR.

R × Angular Separation

= 5,550 km (3,449 miles)

Why are airplane flight paths curved on flat maps?

A curved line on a 2D Mercator map represents the straightest and shortest 3D distance across a spherical Earth.

Calculate total gas cost, fuel volume required, and per-mile driving expenses for any road trip itinerary.

Calculate flight time, great circle geodesic distance, and estimated airborne hours between any global airport coordinates.

Solve for travel time, average travel speed, or distance covered across any transport mode.

Determine true airfare value by calculating the exact cost per mile flown including ticket price, seat selection, and baggage fees.
