The distance between 32 and 78 is sqrt 52 or approximately 721 units. One of the most common ways to calculate distances using latitude and longitude is the haversine formula which is used to measure distances on a sphere. Heres a Code to Calculate Distance between Two Points in C Programming Language.
The linear distance between the two points is the square root of the sum of the squared values of the x-axis distance and the y-axis distance.
Coordinates of Point 1 x 1y 1. X y Calculate the distance between two points by filling in the x and y. X Research source To carry on the example. With just a quick glance you can tell they are 3 units apart.
