GEOGRAPHY & CARTOGRAPHY CALCULATOR
Mori
A precise tool.
What is the Mori & How does it work?
The haversine formula provides a reliable way to calculate the greatβcircle distance between two points on the Earth’s surface using their latitude and longitude.
It accounts for the spherical shape of the planet, making it essential for navigation, GIS analysis, and cartographic scaling.
By converting angular coordinates to radians and applying trigonometric functions, the formula yields distance in the chosen unit (kilometers or miles).
d = 2R \arcsin\left(\sqrt{\sin^2\left(\frac{\phi_2-\phi_1}{2}\right) + \cos\phi_1 \cos\phi_2 \sin^2\left(\frac{\lambda_2-\lambda_1}{2}\right)}\right)
d = distance, R = Earth radius, phi = latitude, lambda = longitude

Frequently Asked Questions
What is the haversine formula used for?
The haversine formula calculates the shortest distance between two points on a sphere, like the Earth, using their latitude and longitude.
How does the haversine formula account for the Earth’s shape?
The haversine formula accounts for the Earth’s spherical shape by converting angular coordinates to radians and applying trigonometric functions to compute the great-circle distance.
Can I use the haversine formula for any two points on Earth?
Yes, you can use the haversine formula for any two points on Earth as long as you have their latitude and longitude coordinates.
What units does the haversine formula output?
The haversine formula outputs distance in kilometers or miles, depending on the unit chosen.
Is the haversine formula suitable for navigation?
Yes, the haversine formula is highly suitable for navigation as it provides a reliable way to calculate distances between two points on the Earth’s surface.
How do I convert degrees to radians for the haversine formula?
To convert degrees to radians, multiply the degree value by Ο/180.
What is the difference between great-circle distance and straight-line distance?
Great-circle distance follows the curvature of the Earth’s surface, while straight-line distance is a hypothetical line through the Earth, ignoring its spherical shape.
