1. What is the Distance Calculator?

The Distance Calculator computes the great-circle distance between two points on the Earth's surface using their latitude and longitude coordinates. This calculation provides the shortest distance between two points on a sphere.

2. How Does the Calculator Work?

The calculator uses the Haversine formula:

\[ \text{Distance} = 2r \arcsin\left(\sqrt{\sin^2\left(\frac{\Delta\phi}{2}\right) + \cos\phi_1 \cos\phi_2 \sin^2\left(\frac{\Delta\lambda}{2}\right)}\right) \]

Where:

\( r \) — Earth's radius (6371 km)
\( \phi_1, \phi_2 \) — Latitude of point 1 and 2
\( \Delta\phi \) — Difference between latitudes
\( \Delta\lambda \) — Difference between longitudes

Explanation: The formula accounts for the curvature of the Earth to provide accurate distance measurements between geographic coordinates.

3. Importance of Distance Calculation

Details: Accurate distance calculation is crucial for navigation, logistics, travel planning, and geographic analysis. It helps determine the actual travel distance between locations.

4. Using the Calculator

Tips: Enter latitude and longitude coordinates in decimal degrees format (e.g., 40.7128, -74.0060 for New York). Positive values are north/east, negative values are south/west.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: The calculator provides great-circle distance accuracy within about 0.5% of the actual distance, assuming a spherical Earth.

Q2: What coordinate format should I use?
A: Use decimal degrees format (e.g., 34.0522° N = 34.0522, 118.2437° W = -118.2437).

Q3: Can I use this for very short distances?
A: Yes, but for distances under 1 km, flat-earth approximations may be simpler and equally accurate.

Q4: Why is the distance different from driving distance?
A: This calculates straight-line distance. Driving distance accounts for roads, terrain, and obstacles.

Q5: How can I find my coordinates?
A: Use GPS devices, smartphone maps, or online tools like Google Maps (right-click → "What's here?").
