Can I switch units?
Yes—enter coordinates using any consistent unit (meters, feet, etc.) and the distance comes out in the same unit.
Step-by-step walkthrough
Distance Calculator Guide
Use this companion guide beside the interactive calculator to make sure you understand the “why” behind every click. Each section includes the classroom explanation, student-friendly language, and quick practice prompts.
Before you start
Collect the data points listed below and double-check their units. Keeping an organized “givens” list is one of the fastest ways to reduce math errors and impress exam graders.
- distance
- coordinate
- euclidean
Detailed procedure
Step 1
Enter starting point coordinates.
Step 2
Enter ending point coordinates, adding the z values if you need 3D distance.
Step 3
Review the resulting distance along with the component deltas.
Teaching & troubleshooting tips
Does it support geographic coordinates?
This tool uses Cartesian coordinates. For lat/long great-circle distances, use a dedicated haversine calculator.
