Conversion between wind speed measurement units including Beaufort numbers, km/h, m/s, mph, fps.
|Nautical Units Converter
This calculator converts various nautical measurement units. It includes conversions for speed and distance units. For speed, it can convert knots to miles per hour, kilometers per hour, feet per second or meters per second. For distance, it can convert nautical miles to miles, kilometers, cables, leagues, meters or feet.
|Course angle and the distance between the two points on loxodrome (rhumb line).
Calculation of a distance on loxodrome (rhumb line) and course angle (azimuth) between two points with a given geographical coordinates.
|Course angles and distance between the two points on the orthodrome(great circle)
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.
