📘 How Mileage Calculation Works
This calculator determines the distance between two locations using the Haversine formula, which calculates the great-circle distance between two points on a sphere given their longitudes and latitudes.
The formula for calculating distance is:
c = 2 ⋅ atan2( √a, √(1−a) )
d = R ⋅ c
Where:
φ is latitude, λ is longitude, R is earth's radius (6371 km or 3959 miles)
Δφ is the difference in latitudes
Δλ is the difference in longitudes
For fuel calculations, the formula is simple:
Fuel Cost = Fuel Needed × Price Per Gallon
Note that the calculated distance is "as the crow flies" (straight line). Actual driving distance may be longer due to roads, terrain, and routing. For precise driving directions, use the Google Maps or Apple Maps links provided.
Our mileage calculator uses the Haversine formula for great-circle distance calculations, which provides accurate straight-line distance between two points. For driving distances, we integrate with Google Maps to provide actual road distances and routes. The straight-line calculation is typically within 5-10% of actual driving distance for most routes.
For the most accurate driving distance and time, always use the Google Maps link provided, which takes into account current road conditions, traffic, and available routes.
Yes, our advanced mileage calculator includes fuel cost estimation. Simply enter your vehicle's fuel efficiency (miles per gallon or liters per 100km) and the current fuel price, and the calculator will estimate your total fuel cost for the trip based on the calculated distance.
Keep in mind that actual fuel consumption may vary based on driving conditions, vehicle load, traffic, and driving style. The calculation provides a helpful estimate for trip planning purposes.
The calculator provides both straight-line (as the crow flies) distance and integrates with Google Maps for actual driving routes. For precise driving distance, travel time, and route options, use the 'View route on Google Maps' link which will show you various route options including fastest, shortest, and avoiding tolls or highways.
For specialized routing needs (like truck routes, EV charging stations, or scenic routes), we recommend using dedicated navigation apps that specialize in those route types.
Straight-line distance represents the shortest path between two points, ignoring geographical obstacles, road networks, and infrastructure. Driving distance follows available roads, which often include detours, curves, and sometimes longer routes to avoid obstacles like mountains, bodies of water, or private property.
In urban areas, the difference is usually smaller (10-20%), while in rural or mountainous areas, the driving distance can be 30-50% longer than the straight-line distance due to terrain constraints.
Yes, the calculator works for locations worldwide. The distance calculation uses coordinates, so it works regardless of country borders. The Google Maps integration also supports international locations, though the quality of map data may vary in some regions.
For fuel calculations, note that the calculator uses miles and gallons by default. For metric system users, you can mentally convert the results to kilometers and liters (1 mile = 1.609 km, 1 gallon = 3.785 liters).
