Distance is calculated using the Pythagorean theorem applied to the coordinate plane (the distance formula): the square root of (x2-x1)² plus (y2-y1)². Midpoint is simply the average of the two x-coordinates and the average of the two y-coordinates.
Yes, enter any positive or negative coordinate values for either point.
This calculator uses flat-plane (Euclidean) geometry, suited to graph coordinates. Real-world GPS distances over the Earth's curved surface require a different formula (like the Haversine formula) and aren't covered by this tool.
Slope Calculator
Calculate the slope, y-intercept and equation of a line through two points.
Triangle Calculator
