FAQ

What is the distance formula?

d = √((x₂−x₁)² + (y₂−y₁)²) — a direct application of the Pythagorean theorem to the coordinate differences.

Does it work with negative coordinates?

Yes, differences are squared, so signs cancel and any pair of real coordinates works.

Can it do 3D?

This tool covers the 2D plane; for 3D add the squared difference of the z-coordinates under the same root.

Calculate percentages three ways: what is X% of Y, X is what percent of Y, and Y increased or decreased by X%.

Calculate the percentage increase or decrease between two values, with the absolute difference and direction.

Find the percentage difference between two values relative to their average — the symmetric comparison used in science and engineering.
