Distance Between Two Places
Straight-line distance with initial bearing and unit conversion.
By Aryan Khan, Founder & Editor · Updated October 2026
For example, Times Square to Grand Central in New York measures approx. 0.9 km (0.6 miles) — the same formula that returns 3,935.8 km for New York to Los Angeles.
How to use Distance Between Two Places
If it has a location, this tool can measure from it. Two steps:
Distance Between Two Places is the straight-line measure: set any two points on Earth — by search, by clicking the map, or by typing coordinates — and read their great-circle distance in miles and kilometres with the initial bearing. It is the baseline measurement other tools build on.

- 2Read distance and bearing.
What people use Distance Between Two Places for
1. Everyday 'how far' questions
House to school, office to airport, campsite to trailhead: the questions that start arguments at kitchen tables end with one measured number and a bearing.
2. Property research
Distances from a listing to the things that matter — coast, station, family — measured from the actual points, not the postcode's reputation. For postal-code pairs, the Distance Between ZIP Codes tool is the shortcut.
3. Planning buffers and boundaries
A measured separation is the input to radius decisions: once two places are measured, the Map Radius Tool draws what falls inside the same distance from either.
4. Fact-checking other tools
When two apps disagree about a separation, this page is the independent referee: one formula, shown working, no account and no agenda.
Worked examples
Times Square (40.7580, −73.9855) to Grand Central Terminal (40.7527, −73.9772): approx. 0.9 km (0.6 mi), initial bearing 130°. The formula does not change with scale — only the map's zoom does.
The same two clicks at continental scale: New York to Los Angeles returns approx. 3,935.8 km (2,445.6 mi) with the route drawn as the arc it really is. Short and long measurements share one method, which is why both can be trusted the same way.
Reference separations
A scale ladder measured with this tool's method (haversine, R = 6,371.0088 km) — approx. figures from published coordinates.
| Pair | Miles | Kilometres |
|---|---|---|
| Times Square ↔ Grand Central, New York | 0.6 | 0.9 |
| Boston ↔ New York | 190.2 | 306.1 |
| Chicago ↔ Dallas | 804.6 | 1,295.0 |
| New York ↔ Chicago | 711.0 | 1,144.3 |
| New York ↔ Los Angeles | 2,445.6 | 3,935.8 |
| London ↔ Paris | 213.5 | 343.5 |
| London ↔ Berlin | 578.8 | 931.6 |
| Paris ↔ Rome | 686.8 | 1,105.3 |
Notice the ladder: the method is identical from 0.9 km to 3,936 km — only the curvature's visibility changes.
Choose the right meaning of distance before using the number
This calculator measures the shortest surface separation between two places using great-circle geometry. It is appropriate for geographic comparison, aviation-style crow-flight distance, rough regional scale and checking how far apart two coordinates are. It is not the same as road distance, walking distance or scheduled travel time, because transport networks rarely follow the geometric minimum.
Long routes make the distinction especially important: coastlines, mountain passes, islands, border crossings and road layout can add substantial real-world distance. MapBench keeps the straight-line method explicit so you can compare it with routing tools rather than mixing two different concepts into one answer.
How to interpret the result
The most common errors come from using a correct result to answer the wrong geographic question. Keep these points in mind for Distance Between Two Places:
- Use the midpoint tool instead of averaging coordinates when splitting journeys: latitude/longitude averages distort over long legs and fail across the date line, while the spherical midpoint follows the actual path the distance was measured along.
- Always confirm which distance you need before quoting one: straight-line for physical questions, road distance for driving, and network time for schedules. The three can differ by half again in mountainous or island geography, and quoting the wrong one is the most common distance mistake in reports.
Limits & appropriate use
The honest limits here are about category, not quality: great-circle math is near-exact, but it answers 'how far over the surface', not 'how far as driven, flown or walked'. Airline distances follow airways and winds; odometers follow detours; hikers follow switchbacks. Quoting a straight-line number into a fuel budget is the classic misuse, which is why the tools keep the ladder visible — crow-flies, road, time — and label each rung. A second limit is definitional: 'city to city' means mapped centre to mapped centre, and a suburb-to-airport question is a different measurement wearing the same sentence.
Within those bounds the numbers are durable: reproducible from coordinates alone, stable across tools that use the same radius convention, and accurate to a fraction of a percent of geodetic truth. The escalation path is short and rarely needed — ellipsoidal libraries (Karney's algorithms) for survey-grade millimetres, the routing engine for network truth, and the airline's schedule for invoice truth. Knowing which authority owns which number is the entire craft of distance literacy.
- Survey-grade millimetres → ellipsoidal geodesic libraries, not sphere math.
- Fuel and schedule planning → road routing plus your congestion buffer.
- Airline invoicing → carrier distance tables (airways ≠ great circles).
Data & methodology
The workspace calculates a spherical great-circle distance from the two selected coordinates using the haversine formula and a mean Earth radius of 6,371.0088 km; it also calculates bearings and a geographic midpoint. This is not a road route.

Key terms worth knowing
- Haversine
- The standard stable formula for great-circle distance on a sphere.
- Initial bearing
- Compass angle from true north at departure along a great circle.
Editorial guidance: MapBench explains the method and limitations so the tool can be used as a transparent reference, not as a black-box answer. For legal boundaries, safety-critical routing, surveying, engineering, regulated decisions or official statistics, verify the result with the responsible authority or a qualified professional.

What people use a two-place distance calculator for
Flight planning baseline
Great-circle distance is useful for comparing long-haul routes before looking at airline schedules. Actual flight paths can be longer because of winds, airspace restrictions and routing.
Relocation and family travel
Straight-line distance gives a stable geographic baseline between two places. For travel time, compare it with the Driving Distance Calculator.
Service and territory comparison
Use direct distance to compare branches, customers or facilities consistently. For actual coverage, a Drive Time Map or Map Radius Tool may better match the question.
Navigation and bearing checks
The result includes the initial compass bearing and geographic midpoint. For more direction detail, use the Bearing Calculator.
Common city-to-city straight-line distances
These are reproducible MapBench calculations using the same great-circle method as the tool. They are reference values, not road mileage or booked flight distance.
| Route | Miles | Kilometres | Nautical miles |
|---|---|---|---|
| New York → London | 3,461 | 5,570 | 3,008 |
| Los Angeles → Tokyo | 5,480 | 8,819 | 4,762 |
| Sydney → Singapore | 3,919 | 6,306 | 3,405 |
| Paris → Dubai | 3,260 | 5,247 | 2,833 |
| Delhi → London | 4,170 | 6,711 | 3,624 |
| New York → Los Angeles | 2,446 | 3,936 | 2,125 |
How the distance calculation works
MapBench calculates the central angle between the two WGS84 latitude/longitude inputs and converts that angle to surface distance using a mean Earth radius of 6,371.0088 km. This is a spherical great-circle calculation: fast, transparent and appropriate for everyday worldwide distance comparisons.
It is not the same as a full ellipsoidal geodesic solver, and it is not a road-network measurement. For most everyday comparisons the difference from an ellipsoidal geodesic is small, but specialist surveying, engineering or legal work should use dedicated geodesic software and authoritative coordinates.

Method, assumptions & limits
- This tool’s method
- The workspace calculates a spherical great-circle distance from the two selected coordinates using the haversine formula and a mean Earth radius of 6,371.0088 km; it also calculates bearings and a geographic midpoint. This is not a road route.
- Before relying on the answer
- Keep the endpoints and measurement mode fixed when comparing results. A surface separation, a compass bearing and a road distance are different outputs.
- What the result cannot establish
- A rounded coordinate or a city-centre search changes the endpoints. Do not interpret displayed decimal places as survey accuracy.

Frequently asked questions
Clear answers about the calculation, accuracy and appropriate use.
Driving distance?
No — straight-line. Use driving distance for roads.
How accurate is this distance?
The geometric calculation is suitable for planning and comparison, but the answer is only as accurate as the coordinates you provide. Road, terrain and legal distances can differ.
Can I use coordinates instead of place names?
Yes. Where the tool accepts locations, you can paste latitude and longitude directly for a more explicit input.
Why can this differ from Google Maps or a road route?
Straight-line and geodesic tools measure geometry on Earth, while road-routing tools follow an actual transport network. They answer different questions.
What is the most accurate way to set a point?
Coordinates, when you have them: a searched place resolves to its published centre, which for a large town can sit a mile from the street you mean. Clicking the exact spot or pasting coordinates removes that slack.
Why does it differ from my car's odometer?
Your car follows roads; this measures the surface of the Earth. The road figure is always longer, and the ratio between them describes the terrain and network between the points.
Can I measure across the Pacific or the poles?
Yes. The formula is global and handles the antimeridian and high latitudes; the map drawing wraps accordingly. Try your point to its antipode for the longest answer the planet allows.
Does it give the bearing as well?
Yes — the initial great-circle bearing from the first place to the second, the heading you would start on. The Bearing Calculator explores it in both directions.
What about elevation — is the distance over the ground?
It is the surface distance on the mean sphere, without terrain relief. Over any real landscape the walked distance is longer; for planning separations the spherical figure is the standard.
Can I measure more than two places?
For chains and tables, use the Distance Matrix Calculator (every pair at once) or the Multi-Stop Route Planner (a journey in order).
Is there a limit on how close the points can be?
No practical one — the same calculation returns metres for neighbouring buildings and thousands of kilometres for continents.
