Now that you have the latitude and longitude values in decimals, you just face the equation for the nautical miles between Timbuktu and Casablanca, noted underneath. One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet. This screen calculates the angle subtended by an object of known height lying at a particular distance within the observer’s visible horizon or vice versa.The calculation provides the solution of a plane right triangle having its right angle at the base of the observed object and its altitude coincident with the vertical dimension of the observed object. A nautical mile is a unit of length equal to exactly 1,852 meters. It features natural input so you enter a formula just as it would be written on paper. Speed for Measured Mile and Speed, Time, and Distance 3. This is composed of three sections to do classic Time, Speed and Distance calculations. Nautical mile corresponds approximately to one minute of arc of latitude along any meridian. It's the angle between the equatorial plane and a line that is normal to the reference ellipsoid. You can review many of the previous entries you make. Because the Earth being oblate (lense like) spheroid, the length of a nautical mile is longest at the poles, and shortest at equator, see article Ellipsoid for more details on oblate ellipsoids. For example if you wish t… When the navigator wished to determine the speed of his vessel, a sailor dropped the chip log over the stern of the ship. By contrast, the distance of nautical miles between degrees of longitude is not constant because lines of longitude become closer together as … Distance … That brings us back to the 1 In 60 Rule. It was originally based on one minute (1/60th) of a degree of latitude. The calculator computes distance in Statute Miles, Nautical Miles and Kilometres. A nautical mile is based on the circumference of the Earth and is used by sea and air navigators. The calculation uses plane oblique and right triangles to calculate the distance to the object at the second bearing and the distance to the object when abeam. This MATLAB function converts distances from radians to nautical miles, as measured along a great circle on a sphere with a radius of 3440.065 nm, the mean radius of the Earth. You can change your choice at any time on our. Thus, degrees of latitude are approximately 60 nautical miles apart.
