Questions
Is 2,131 km (1,324 miles) the driving distance from Adelaide to Perth?
No. 2,131 km (1,324 miles) is the straight-line distance between the two city centres, as the crow flies. A road route is always longer, because roads bend around terrain and water, and MapGO does not measure driving distance or travel time.
How is the distance between Adelaide and Perth measured?
Along a great circle: the shortest line over the Earth's surface, from Adelaide's centre (34.9287° S, 138.5986° E) to Perth's (31.9522° S, 115.8614° E). This is what "straight-line distance" and "as the crow flies" mean on a globe. On a flat map the line can look curved.
How accurate is this distance?
Within about 0.5% for the two centre points. The figure treats the Earth as a sphere (the haversine formula), while the real Earth is slightly flattened, which shifts a long straight-line distance by up to about 0.5%. Measuring from another part of either city changes it more, since a large city can be tens of kilometres across.
Computed by MapGO from each city's centre point (GeoNames) with the haversine formula. All distances on this page are straight lines over the Earth's surface, not road distances.
