Online calculation tool for spherical distance between two points on the earth


Originating place
Destination

On the equator of the earth, it takes a circle of 40075.04 kilometers around the earth, and @ circle is divided into 360°. And every 1 ° (degrees) has 60, the length of each degree and one second on the equator is calculated as follows:

40075.04km/360°=111.31955km

111.31955km/60=1.8553258km=1855.3m

Each minute has 60 seconds, and each second represents 1855.3m/60=30.92m.

The formula for calculating the distance between any two points is

\(d=111.12cos{1/[sinΦAsinΦB十cosΦAcosΦBcos(λB—λA)]}\)

The longitude and longitude of point A are λA and ΦA, respectively, and the longitude and latitude of point B are λB and ΦB, respectively, and d is the distance.
