If we stick with the geometrical definition of distance we nevertheless have to define what sort of space we're operating in. In maximum cases, you're probably speakme about three dimensions or less, for the reason that that's all we can consider without our brains exploding. Distance Formula Calculator For this calculator, we focus handiest at the 2D distance (with the 1D included as a unique case). If you're searching out the three-D distance between 2 points we encourage you to use our 3-d distance calculator made especially for that purpose.
