1. What is the Distance Formula?

The distance formula calculates the straight-line distance between two points in a 2D plane. This calculator specifically converts the result from meters to miles, which is useful for geographic distance measurements.

2. How Does the Calculator Work?

The calculator uses the Euclidean distance formula:

Where:

• \( (x_1, y_1) \) — Coordinates of first point in meters
• \( (x_2, y_2) \) — Coordinates of second point in meters
• 1609.34 — Conversion factor (meters to miles)

Explanation: The formula calculates the straight-line distance between two points and converts it from meters to miles.

3. Importance of Distance Calculation

Details: Calculating distances between points is fundamental in navigation, mapping, logistics, and many scientific applications. Converting to miles is particularly useful for transportation planning and geographic measurements in countries using imperial units.

4. Using the Calculator

Tips: Enter coordinates for both points in meters. The calculator accepts decimal values for precise measurements. Negative values can be used for coordinates west of the prime meridian or south of the equator.

5. Frequently Asked Questions (FAQ)

Q1: What coordinate system should I use?
A: This calculator works with any Cartesian coordinate system where both points use the same reference frame. For geographic coordinates, convert to UTM or another projected system first.

Q2: How accurate is this calculation?
A: The calculation is mathematically precise for flat-plane distances. For Earth's surface, it's an approximation that works best for short distances (under 100 km).

Q3: Why convert to miles?
A: Miles are commonly used in the United States and some other countries for road distances and other everyday measurements.

Q4: Can I use this for 3D coordinates?
A: This calculator only handles 2D coordinates. For 3D, you would need to add a z-component to the formula.

Q5: What's the maximum distance this can calculate?
A: There's no technical limit, but for very large distances, Earth's curvature makes the flat-plane calculation increasingly inaccurate.
