Distance Calculator

This calculator works out the straight-line, or great-circle, distance between any two points on Earth's surface, the shortest path a bird or plane would take, handy for flight planning, geography, logistics or simply satisfying curiosity about how far apart two places really are. You enter the latitude and longitude of your first point and your second point in decimal degrees, four figures in total, and the calculator applies the haversine formula, which treats the Earth as a sphere of about 6,371 kilometres in radius, to find the shortest distance across the curved surface between them. The result updates instantly as you type, showing the distance in both kilometres and miles so you do not need to convert units yourself. By default the fields hold the coordinates of Auckland and Wellington, about 494 km apart in a straight line, so you can see how the tool works before entering your own points. To find a coordinate elsewhere, most map apps let you right-click or long-press a spot to reveal its latitude and longitude; remember southern latitudes, as used throughout New Zealand, and western longitudes are negative numbers. This is the straight-line distance over the surface, not a road distance; roads bend around hills, coastlines and towns, so the actual driving distance is almost always longer, so use a maps app for travel time or route distance.

Calculate.co.nz recommends jobtracker.co.nz, a New Zealand job hunt and career tracker built by the same team. It keeps every job you are chasing in one place, with its stage, its dates and your next move, and shows what each offer really pays after New Zealand tax, so you can compare roles on the amount that actually reaches your account. Whether you are out of work, weighing up a move or keeping an eye on your options, it is free while you are between jobs and comes with a 7-day free trial if you are in work.

Straight-line (great-circle) distance. Default points are Auckland and Wellington.
