Δx (run) = 6 cmHow to use the Distance, Midpoint & Slope
- Pick the unit your measurements use. All dimensions must share the same unit.
- Enter x₁, y₁, x₂ and y₂. Focus a field to highlight the matching label on the diagram.
- Read the results as you type. The largest card is the main answer; the others are the related measurements.
- Copy a single value, copy everything, or share a link that keeps your inputs.
Distance, Midpoint & Slope FAQ
What formulas does the distance, midpoint & slope use?
d = √((x₂−x₁)² + (y₂−y₁)²); M = ((x₁+x₂)/2, (y₁+y₂)/2); m = (y₂−y₁) / (x₂−x₁).
Can I use different units?
Yes. Pick the input unit and, if you like, a different output unit. Area results are shown in squared units and volumes in cubed units.
Is this distance, midpoint & slope free and private?
Yes. It is free with no sign-up, and calculations happen on your device, so your numbers are never sent to a server.
