1. What is the Distance Calculator?

This calculator determines the straight-line distance between two points on a 2D plane, useful for finding how far you are from stores that sell calculator batteries or other locations.

2. How Does the Calculator Work?

The calculator uses the Euclidean distance formula:

Where:

• \( x_1, y_1 \) — Your current location coordinates
• \( x_2, y_2 \) — Store location coordinates

Explanation: The formula calculates the straight-line distance between two points in a 2-dimensional space.

3. Importance of Distance Calculation

Details: Knowing the distance to stores selling calculator batteries helps in planning your trip, estimating travel time, and finding the nearest location.

4. Using the Calculator

Tips: Enter your current location coordinates and the store coordinates (in kilometers). Many mapping services provide these coordinates.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find coordinates for my location?
A: Most mapping apps (Google Maps, Apple Maps) show coordinates when you long-press a location.

Q2: Is this driving distance?
A: No, this calculates straight-line (as-the-crow-flies) distance. Actual travel distance may be longer.

Q3: What coordinate system should I use?
A: Any consistent coordinate system works (UTM, latitude/longitude), but both points must use the same system.

Q4: Can I use negative coordinates?
A: Yes, the formula works with any real numbers, including negatives.

Q5: How accurate is this for large distances?
A: For distances over 20km, Earth's curvature affects accuracy. Consider using haversine formula for global distances.
