About This Distance Calculation
The distance between Beijing and Nanjing is calculated using the Haversine formula, which determines the great-circle distance between two points on a sphere given their latitude and longitude coordinates. This represents the shortest distance over the earth's surface, giving an "as-the-crow-flies" distance of approximately 898 kilometers (558 miles).
This calculation assumes the Earth is a perfect sphere (it's actually slightly flattened at the poles), but the Haversine formula is accurate to within 0.5% for distances between most points on Earth. The coordinates used are:
- Beijing: °N, °W
- Nanjing: °N, °W
Keep in mind that actual travel distances by car, train, or ship will be longer due to the need to follow roads, railways, shipping routes, and navigate around geographical obstacles. Flight paths may also differ from the great circle route due to air traffic control requirements, weather conditions, and airline-specific routing policies.
