Haversine Formula
The calculator uses the Haversine formula to calculate great-circle distance between two points:
a = sin²(Δφ/2) + cos φ₁ ⋅ cos φ₂ ⋅ sin²(Δλ/2)
c = 2 ⋅ atan2(√a, √(1−a))
d = R ⋅ c
c = 2 ⋅ atan2(√a, √(1−a))
d = R ⋅ c
Where φ is latitude, λ is longitude, and R is Earth's radius (6371km)

Understanding Your Results: A Deep Dive
Great Circle Distance Explained
Your primary result shows the great-circle distance—the shortest path between two points on a sphere. This differs from straight-line distance on flat maps because Earth is curved. For example, the great-circle route from New York to Tokyo passes over Alaska, not directly across the Pacific.
Bearing and Navigation
The initial bearing indicates your starting direction when traveling from point A to point B. Bearings are measured clockwise from north (0° to 360°). This information is crucial for compass navigation and plotting courses.
Midpoint Coordinates
The midpoint is the geographic center between your two points. This is useful for meeting points, planning layovers, or finding the average location of multiple sites.
Travel Time Estimates
Our calculator estimates driving time assuming average speeds of 60 km/h (37 mph). Actual times vary based on road conditions, traffic, and terrain. Use this as a planning baseline, not a guarantee.
Pro Tips for Maximum Accuracy
Coordinate Precision
Enter coordinates with at least 4 decimal places for meter-level accuracy. Each decimal place represents approximately:
- 1 degree = 111 kilometers
- 0.1° = 11.1 km
- 0.01° = 1.11 km
- 0.001° = 111 meters
- 0.0001° = 11.1 meters
Format Conversion Best Practices
When converting between coordinate formats, always double-check your results. A common mistake is confusing minutes and seconds (1 minute = 60 seconds, not 100). Our converter handles these calculations automatically to prevent errors.
Elevation Considerations
For every 100 meters of elevation gain, add approximately 0.1% to your distance calculation. This becomes significant in mountainous terrain where cumulative elevation change can exceed 2,000 meters.
Batch Processing
For multiple calculations, keep your browser tab open. Our calculator maintains your last inputs, and you can use browser autofill or copy-paste to quickly process coordinate lists.
Cross-Referencing Results
Always verify critical measurements using multiple sources. While our calculator is highly accurate, human input errors can occur. Double-check coordinate signs (+/-) and decimal placement.

Can I save my calculations?
Yes! Use the social sharing feature to generate a unique URL containing your coordinates. Bookmark this URL or share it via email to access the exact calculation anytime. The URL parameters preserve all your input data.
Why does the road distance differ from the great-circle distance?
Roads follow terrain, avoid obstacles, and follow legal routes. The 15% adjustment approximates real-world driving distances based on empirical data. For exact driving distances, use our interactive map link to open directions in OpenStreetMap.
Is my location data stored or shared?
No. All calculations happen locally in your browser. We do not store, transmit, or share your coordinate data. When you use social sharing, only the coordinates you explicitly share are included in the generated link.
What’s the difference between UTM and lat/long coordinates?
UTM (Universal Transverse Mercator) is a projected coordinate system dividing Earth into zones. It’s excellent for local measurements but requires zone information. Lat/long (geographic coordinates) works globally without zones but calculations are more complex. Our tool converts between them seamlessly.
How do I find coordinates for an address?
Use Google Maps, Apple Maps, or OpenStreetMap. Right-click any location to see its coordinates. Alternatively, use our interactive map preview after entering approximate coordinates, then drag markers to fine-tune positions.
Can the calculator handle coordinates in space or on other planets?
Currently, the calculator is optimized for Earth-based coordinates using Earth’s radius. For educational purposes, you could adapt the formula for other celestial bodies by changing the radius constant.
What should I do if I get an error message?
Check that your latitudes are between -90° and +90° and longitudes between -180° and +180°. Verify decimal points aren’t accidentally typed as commas. Ensure DMS fields don’t exceed 59 minutes or seconds.
How often should I calibrate my GPS device for accurate coordinates?
Consumer GPS devices typically achieve 3-5 meter accuracy. For survey-grade precision (centimeter-level), use differential GPS (DGPS) or real-time kinematic (RTK) systems. Our calculator’s precision exceeds that of standard GPS devices.
Can I use this calculator for commercial purposes?
Absolutely! The calculator is free for personal and commercial use. Developers can integrate similar functionality into applications using the Haversine formula implementation provided in our code.
Why does the bearing change as I travel?
The initial bearing is calculated at your starting point. As you follow a great-circle route, your heading continuously changes to stay on the shortest path. This is why long-haul flights appear curved on flat maps.
How does elevation affect distance calculations?
At 1,000 meters elevation, the Earth’s radius increases by about 0.016%. Over long distances in mountains, this can affect measurements by several meters. Our optional elevation adjustment accounts for this variation.
What’s the fastest way to enter coordinates from my phone?
Use your phone’s GPS to get current coordinates, tap and hold to copy, then paste directly into our calculator. The mobile-optimized interface automatically formats inputs for touchscreen users.
