For most calculations, 6,000 feet is close enough. A nautical mile is based on the circumference of the Earth and is used by sea and air navigators. How to convert Kilometers to Nautical Miles? The log-line has a number of knots tied in it at uniform spacings (47 feet and 3 inches or 14.4 meters). This is composed of three sections to do classic Time, Speed and Distance calculations. The Casio has 1 memory position but there are 8 positions for variables so you have 9 memory locations. radian = degree * (PI/180.0); where PI is 3.141592. Distance on water is measured in nautical miles (NM or nm). For example if you wish t… Learn how PLANETCALC and our partners collect and use data. You can review many of the previous entries you make. The geographic range depends upon the height of both the light and the eye of the observer. This script will calculate the length of one degree of both latitude and longitude, for a specific latitude. Distance calculator helps you to find how many miles from a city to an another city on map.. 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. International nautical mile consists of 10 cables (1 cable=185.2 meters ). A nautical mile is a measurement of distance that is equal to “one minute” of latitude. 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 calculation gives the length of one degree of latitude and longitude at intervals of 1° from the equator to the poles.

It's the angle between the equatorial plane and a line that is normal to the reference ellipsoid. A nautical mile can also be described as the distance traveled over 1 minute with a speed of one knot. Distance … There are 0.86897583 nautical miles in a mile. The international nautical mile was defined by the First International Extraordinary Hydrographic Conference, Monaco (1929) as exactly 1852 metres. Distance in yards and feet is calculated from the corrected vertical angle and the height of eye of the observer in nautical miles. Currently international knot is defined as 1.852 km/h (one nautical mile per hour). Use the miles / km / nautical miles / yards switch to measure distances in km or in miles or nautical miles.

So if you need to descend 400 feet in 4NM, that means you need to descend 100 feet per nautical mile (400/4=100). Simply click once on one point, then click again on the second point. To find the speed of a vessel on a measured nautical mile in a given number of minutes and seconds of time, enter the time in total seconds (i.e., 90 = 1 min 30 sec), and the calculation will produce speed in knots. One degree (°) is equal to 60 minutes (') and equal to 3600 seconds ("): 1° = 60' = 3600" The integer degrees (d) are equal to the integer part of the decimal degrees (dd): d = integer(dd) Also, the formula used contains an approximation which introduces a small error at the greatest heights tabulated. Formula To Convert Degree … It was originally based on one minute (1/60th) of a degree of latitude. Lengths are given in nautical miles, statute miles, feet, and meters.The values were computed in meters, using the World Geodetic System ellipsoid of 1972, and converted to other units. A minute of arc, arcminute (arcmin), arc minute, or minute arc, denoted by the symbol ′, is a unit of angular measurement equal to 1 / 60 of one degree. Our online km to nautical miles converter is a great. Sea Distance Calculator. A vessel travelling at 1 knot along a meridian travels one minute of geographic latitude in one hour (or one sea mile per hour). This screen calculates the distance to an object lying within or short of the horizon when the height of eye of the observer is known. This calculator will help you calculate meridional parts which are used in Mercator charts and Mercator navigation. By contrast, the distance of nautical miles between degrees of longitude is not constant because lines of longitude become closer together as … Online calculator to convert nautical miles to miles (nmi to mi) with formulas, examples, and tables. The log-line was allowed to run out for a fixed period of time. 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. 43°32.9999 N: 7°05.9999 E: 43°32'59.99" N: 7°5'59.99" E: i Then enter the speed value and conversion designation for it. nautical miles.

However, the error is generally less than that introduced by nonstandard atmospheric conditions. Lengths are given in nautical miles, statute miles, feet, and meters. Every 1 degree of descent is going to give you 100 feet per nautical mile. The vertical angle between the water-line at the object and the visible (sea) horizon beyond is measured and corrected for index error. You can change your choice at any time on our. If land, another vessel, or other obstruction is between the observer and the sea horizon, use the waterline of the obstruction as the horizontal reference for altitude measurements, and substitute dip from this calculation for the dip of the horizon (height of eye correction) given in the Nautical Almanac. This screen allows calculation of the meridional parts used in the construction of Mercator charts and in Mercator sailing for each minute of latitude from the equator to the poles.Enter the latitude for which the meridional part is desired. One minute of latitude equals one nautical mile and degrees of latitude are 60 nm apart. The values were computed in meters, using the World Geodetic System ellipsoid of 1972, and converted to other units. We convert it to radians. The sea mile is the distance of one minute of arc of latitude at a given latitude and along the current meridian. So when you cross HALFF on your way to PYYPP, pitch your plane down 1 degree, and you're on your way. Nautical mile. This calculator requires the use of Javascript enabled and capable browsers.

A mile is a unit of distance equal to 5,280 feet or exactly 1.609344 kilometers. At first glance it may seem contrary - one minute arc length must be longer at equator, because the equatorial Earth radius is longer than polar one. Distance of an Object by Two Bearings 4. 1. This advanced GPS Coordinate Converter makes it easy to work with map coordinates.It is perfect for converting geographic coordinate formats, and for measuring distance and bearing between coordinates. To convert kilometers to nautical miles, divide the measurement in km by 1.852 to get the equivalent distance in nautical miles. Visit here for more details The distance gradually shrinks to zero as they meet at the poles. Lengths for both are calculated in nautical miles, statute miles, feet, and meters. Nautical mile corresponds approximately to one minute of arc of latitude along any meridian. One nautical mile corresponds to one minute of latitude. The vertical angle between the top of the object and the visible horizon is measured with a sextant and corrected for index error and dip only. By comparison, a statute mile is 5,280 feet or about 87% of a nautical mile and a kilometre is 54%. At 38 degrees North latitude: One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. ...

The following calculator approximates the sea mile length at a given geographic latitude: The knot is a unit of speed, widely used in navigation. The program is operated by entering two geographic points and then pressing the Calculate button. Distance in meters or international nautical miles. The solutions are based upon the following simplifying assumptions: (1) the eye of the observer is at sea level, (2) the sea surface between the observer and the object is flat, (3) atmospheric refraction is negligible, and (4) the waterline at the object is vertically below the peak of the object. This calculation tabulates the distance to an object of known height above sea level when the object lies beyond the horizon. It is approximately one minute of arc measured along any meridian. It features natural input so you enter a formula just as it would be written on paper.
