![]() ![]() Note that neither the haversine formula nor Lambert's formula provides an exact distance because it is not possible to account for every irregularity on the surface of the Earth. In the expressions above, β 1 and β 1 are reduced latitudes using the equation below: Where a is the equatorial radius of the ellipsoid (in this case the Earth), σ is the central angle in radians between the points of latitude and longitude (found using a method such as the haversine formula), f is the flattening of the Earth, and X and Y are expanded below. When used to approximate the Earth and calculate the distance on the Earth surface, it has an accuracy on the order of 10 meters over thousands of kilometers, which is more precise than the haversine formula. Air distance (also called great circle or. Lambert's formula (the formula used by the calculators above) is the method used to calculate the shortest distance along the surface of an ellipsoid. Distance calculator finds the distance between cities or places and shows the distance in miles and kilometers. Because of this, Lambert's formula (an ellipsoidal-surface formula), more precisely approximates the surface of the Earth than the haversine formula (a spherical-surface formula) can. Results using the haversine formula may have an error of up to 0.5% because the Earth is not a perfect sphere, but an ellipsoid with a radius of 6,378 km (3,963 mi) at the equator and a radius of 6,357 km (3,950 mi) at a pole. Canada Driving Distance Calculator, calculates the Distance and Driving Directions between two addresses, places, cities, villages, towns or airports in Canada. The great-circle distance is the shortest distance between two points along the surface of a sphere. It is formed by the intersection of a plane and the sphere through the center point of the sphere. A great circle (also orthodrome) of a sphere is the largest circle that can be drawn on any given sphere. The haversine formula works by finding the great-circle distance between points of latitude and longitude on a sphere, which can be used to approximate distance on the Earth (since it is mostly spherical). ![]() In the haversine formula, d is the distance between two points along a great circle, r is the radius of the sphere, ϕ 1 and ϕ 2 are the latitudes of the two points, and λ 1 and λ 2 are the longitudes of the two points, all in radians. The haversine formula can be used to find the distance between two points on a sphere given their latitude and longitude: There are a number of ways to find the distance between two points along the Earth's surface. Given the two points (1, 3, 7) and (2, 4, 8), the distance between the points can be found as follows: d =ĭistance between two points on Earth's surface Like the 2D version of the formula, it does not matter which of two points is designated (x 1, y 1, z 1) or (x 2, y 2, z 2), as long as the corresponding points are used in the formula. Where (x 1, y 1, z 1) and (x 2, y 2, z 2) are the 3D coordinates of the two points involved. The distance between two points on a 3D coordinate plane can be found using the following distance formulaĭ = √ (x 2 - x 1) 2 + (y 2 - y 1) 2 + (z 2 - z 1) 2 For example, given the two points (1, 5) and (3, 2), either 3 or 1 could be designated as x 1 or x 2 as long as the corresponding y-values are used: The order of the points does not matter for the formula as long as the points chosen are consistent. Where (x 1, y 1) and (x 2, y 2) are the coordinates of the two points involved. One kilometer is equal to 1/1.609344 miles: 1km 1km/1.609344 0.6213712mi How to convert 10mi to kilometers Multiply 10 miles by 1.609344 to get kilometers: 10mi 10mi × 1.609344 16. So add 144 + 13 + 5 = 162 kilometers in 100 miles.The distance between two points on a 2D coordinate plane can be found using the following distance formula The Fibonacci number following 89 is 144, the Fibonacci number following 8 is 13 and Fibonacci number following 3 is 5. Number 100 could be a sum of Fibonacci numbers 89 + 8 + 3. The distance between two points can also be. These km units are used in metric systems. Say you want to convert 100 miles to kilometers. The SI unit used to measure distance or length is known as Kilometre. In order to convert a number that isn't a Fibonacci number, express the original number as a sum of Fibonacci numbers and do the conversion for each Fibonacci number separately.This would tell you there are 34 kilometers in 21 miles and vice versa, when the exact answer is 33.79 kilometers. For example, take the consecutive Fibonacci numbers 21 and 34. To convert back, read the result in the other direction, as there are 5 miles in 8 km. Start with two consecutive Fibonacci numbers.These numbers are a series of numbers in which each subsequent number is the sum of the two before. Use Fibonacci numbers to do the conversion.
