Calculation of azimuth and solar elevation angle by given the coordinates and time of observation. It's possible to input coordinates manually or by selecting from the directory of cities.

The Triangle Angle Calculator is a tool that calculates the angles of a triangle given the length of its sides.

Calculates the distance between two points of the Earth specified geodesic (geographical) coordinates along the shortest path - the great circle (orthodrome). Calculates the initial and final course angles and azimuth at intermediate points between the two given.

This online calculator determines the lengths of triangle sides given one side and two angles using the law of sines.

This online calculator converts the value of an angle given in the degrees-minutes-seconds to degrees, expressed in decimal fraction and back from decimal fraction to degrees-minutes-seconds.

Calculator computes the diagonals of a parallelogram and adjancent angles from side lengths and angle.
