1. What is Distance Between Two Points?

The distance between two points in a plane is the length of the straight line connecting them. This fundamental geometric concept has applications in navigation, mapping, physics, and many other fields.

2. How Does the Calculator Work?

The calculator uses the Euclidean distance formula:

Where:

• \( (x_1, y_1) \) — Coordinates of Point 1
• \( (x_2, y_2) \) — Coordinates of Point 2

Explanation: The formula calculates the straight-line distance between two points in a 2D plane using the Pythagorean theorem.

3. Importance of Distance Calculation

Details: Calculating distances between points is essential for route planning, GPS navigation, computer graphics, physics simulations, and many scientific applications.

4. Using the Calculator

Tips: Enter the coordinates for both points in the same units. The calculator will return the distance in those same units.

5. Frequently Asked Questions (FAQ)

Q1: Can this calculator work for 3D coordinates?
A: This version calculates 2D distances only. For 3D, the formula would include a z-coordinate component.

Q2: What coordinate system does this use?
A: The calculator works with Cartesian coordinates in any consistent unit system (meters, feet, miles, etc.).

Q3: How accurate are the results?
A: Results are accurate to two decimal places. For higher precision, enter more decimal places in the coordinates.

Q4: Can I calculate distances on a spherical surface (like Earth)?
A: This calculates straight-line distances on a flat plane. For great-circle distances on a sphere, a different formula is needed.

Q5: What if my points have negative coordinates?
A: Negative coordinates work fine. The calculator handles all real numbers.
