Example
Example: New York to Los Angeles, 2,445 miles as the crow flies
From: New York, To: Los Angeles, Unit: Miles.
- Straight-line distance: 2,445 mi, which is 3,935 km or 2,125 nautical miles.
- Initial direction: W, 274°. The halfway point is 39.51° N, 97.16° W, in Kansas.
- Flight time: about 5 h 25 min, the distance at 800 km/h plus 30 minutes for take-off and landing. Los Angeles is 3 h behind New York.
| Route | As the crow flies | Flight estimate |
|---|---|---|
| Chicago – Miami | 1,192 mi (1,918 km) | 2 h 55 min |
| Dallas – Denver | 662 mi (1,066 km) | 1 h 50 min |
| Seattle – Boston | 2,485 mi (4,000 km) | 5 h 30 min |
| San Francisco – Honolulu | 2,395 mi (3,854 km) | 5 h 20 min |
| Toronto – Vancouver | 2,087 mi (3,359 km) | 4 h 40 min |
| London – Edinburgh | 331 mi (533 km) | 1 h 10 min |
| London – New York | 3,461 mi (5,570 km) | 7 h 30 min |
| Sydney – Perth | 2,045 mi (3,291 km) | 4 h 35 min |
2,445 miles in a straight line between the two city centres. The drive is a good deal longer, because roads do not follow the great circle.
How it works
- Type two cities — or coordinates such as 48.86, 2.35 for any other place.
- Choose kilometres, miles or nautical miles.
- Read the straight-line distance, the direction to fly, the midpoint, the time difference and a rough flight time.
Frequently asked questions
- How far is Paris from Tokyo?
- About 9,712 km (6,035 miles) in a straight line, roughly 12 h 40 min by air. London to New York is about 5,570 km; Madrid to Barcelona 505 km.
- Is this the driving distance?
- No — it is the great-circle distance over the Earth’s surface, “as the crow flies”. Roads are longer, often by a quarter or more.
- How is the flight time estimated?
- Distance at 800 km/h plus 30 minutes for take-off and landing. Real flights vary with winds, routes and stops.
- How accurate is the distance?
- It is worked out on a round Earth, within about 0.5 % of the true distance on the ellipsoid — a few kilometres on a long flight.
- What if my town is not found?
- Type its coordinates instead, latitude first, such as 40.71, -74.01; a minus sign means south or west. The distance is the same as for the city, and the time zone is guessed from the nearest listed city.
- Why does the direction say 274° and not simply west?
- It is the direction you set off in. The shortest path over a globe is a curve on a flat map, so the heading changes along the way: New York to Los Angeles starts at 274°, a touch north of west, and London to New York at 288°, west-northwest.
