Convert kilometers to degrees
With this online calculator, you can convert degree to kilometers (degree to km) and vice versa.
Formula:
L = π * R * a / 180
L - arc length [km];
R - radius of a circle [km];
a - angle [degrees].
A circle is the set of all points in a plane that are at a given distance from a centre.
Reference data:
The length of the meridian is 0-360 = 40008.55 km;
