Note
Driving estimates are approximations based on highway speeds and typical road routing factors. Actual driving times and distances will vary based on specific routes, traffic, and road conditions.
How to Use

Understanding Latitude
Latitude measures how far north or south a point is from the equator. Values range from -90° (South Pole) to +90° (North Pole).
Positive values = North of equator
Negative values = South of equator
The Equator is at 0° latitude
Understanding Longitude
Longitude measures how far east or west a point is from the Prime Meridian. Values range from -180° to +180°.
Positive values = East of Prime Meridian
Negative values = West of Prime Meridian
The Prime Meridian runs through Greenwich, UK

How Distance Calculation Works
We use the Haversine formula to calculate the great-circle distance — the shortest path between two points on a sphere
1
Spherical Earth Model
Treats Earth as a sphere with average radius of 6,371 km
2
Great Circle Path
Calculates the shortest path along Earth's curved surface
3
High Accuracy
Results accurate within 0.5% for most practical purposes

About Driving Time Estimates
Driving time estimates use average highway speeds and include a factor for non-straight routes.
Note: Actual travel times vary based on roads, traffic, terrain, and stops. Use navigation apps for precise trip planning.
Frequently Asked Questions
What's the difference between straight-line and driving distance?▼
Straight-line distance (also called "as the crow flies") is the shortest possible path between two points. Driving distance follows actual roads and is typically 20-40% longer, depending on terrain and road infrastructure.
How accurate is the Haversine formula?▼
The Haversine formula assumes Earth is a perfect sphere, which provides accuracy within 0.5% for most distances. For very precise surveying, ellipsoidal calculations using the WGS84 model would be needed.
Can I calculate distances for very short distances?▼
Yes, but for distances under 100 meters, GPS precision limitations become significant. For precise short-distance measurements, specialized surveying equipment is recommended.
