Directions Distance Calculator

Place names have to be geocoded by a maps provider, so this calculator takes coordinates.
IUGG mean radius by default. Use 6371 to match textbook worked examples.
If you have the routed road distance, enter it here and it is used instead of the circuity estimate. 0 means estimate it.
How much longer the road is than the straight line. Around 1.2 for typical urban road networks; higher in mountains, along coasts or across water.

Worked out from R. W. Sinnott, "Virtues of the Haversine", Sky and Telescope 68(2), 159 and 3 other sources.
The road distance is an estimate: the straight line multiplied by a circuity factor. Real road distance depends on the actual network and can differ substantially, especially across water, mountains or a coastline. Enter the routed distance from a maps provider for a real figure.
Driving time here is constant-average-speed arithmetic. It accounts for no traffic, road works, weather or rest requirements, and is not an arrival guarantee.

How this is worked out

4 steps
  1. Great-circle distance between the two points on a sphere of radius 6371.0088 km: 2445.5627 mi.
  2. Initial bearing 65.92 degrees (ENE).
  3. Estimated road distance = 2445.563 x 1.2 = 2934.675 mi.
  4. At 60 mph that is 48.911 hours of driving - 48 h 55 min.
