Formula Used

Haversine Surface Distance

a = sin²(Δφ / 2) + cos(φ1) × cos(φ2) × sin²(Δλ / 2)

c = 2 × atan2(√a, √(1 − a))

Surface distance = R × c

R is Earth radius. This calculator uses 6371.0088 kilometers. φ means latitude in radians. λ means longitude in radians.

Three Dimensional Distance

3D distance = √(surface distance² + elevation difference²)

Elevation is converted from meters to kilometers before combining it with surface distance.

Route Adjusted Distance

Route adjusted distance = surface distance × route factor

A factor of 1.00 means direct movement. A factor above 1.00 allows for bends, roads, detours, or access limits.

Travel Time

Travel time = route adjusted distance ÷ average speed

Sheet Formula Example

=6371.0088*2*ASIN(SQRT(POWER(SIN(RADIANS(C2-A2)/2),2)+COS(RADIANS(A2))*COS(RADIANS(C2))*POWER(SIN(RADIANS(D2-B2)/2),2)))

In this sheet formula, A2 is first latitude, B2 is first longitude, C2 is second latitude, and D2 is second longitude.

Address Distance Planning for Sheet Workflows

Distance between two address points is often needed before routing, site checks, delivery costing, field surveys, or physics based motion estimates. This calculator is designed for sheet style work. You enter the address labels, coordinates, elevation values, route factor, and speed. The tool returns surface distance, three dimensional straight line distance, route adjusted distance, bearing, central angle, chord distance, and estimated travel time.

Why Coordinates Matter

Street addresses are names. Physics calculations need numbers. Latitude and longitude convert each point into a position on Earth. The Haversine method then estimates the curved surface distance between both positions. Elevation adds vertical separation. That extra height difference can matter for drone planning, cable runs, slope checks, surveying, and mountain routes. For normal city travel, elevation usually changes the result only slightly.

Sheet Friendly Inputs

Many teams store origin and destination details in spreadsheets. A row may contain origin address, destination address, latitude, longitude, elevation, route factor, and expected speed. The same structure is used here. You can copy values from a sheet, calculate a pair, and download results as CSV. The CSV file can then be reopened in spreadsheet software for reports, invoices, or field records.

Route Factor and Physics

Straight line distance is rarely the same as road distance. Roads bend, avoid barriers, follow grades, and use bridges. The route factor is a practical multiplier. A value of 1.00 means direct movement. A value of 1.25 means the practical route is twenty five percent longer than the surface distance. Travel time is then estimated by dividing adjusted distance by speed.

Best Use Cases

Use this calculator for quick planning, teaching, route comparison, and sheet based estimates. It is not a live geocoding tool. You should get latitude and longitude from a trusted map source first. For legal surveys, air navigation, emergency routing, or engineering approval, confirm results with certified data and specialist software. The calculator is still valuable for fast checks, because it shows every key intermediate value and makes the assumptions visible.

Accuracy Tips

Use degrees, not degrees and minutes. Keep north and east positive. Keep south and west negative. Record elevation in meters. Use the same coordinate source for both points.

FAQs

1. Can this calculator convert street addresses into coordinates?

No. It does not geocode addresses. Enter latitude and longitude from a trusted map source, survey file, or sheet column before calculating distance.

2. Why is the route distance longer than surface distance?

Surface distance is direct curved distance between points. Route distance uses the route factor. It allows for roads, turns, bridges, access limits, and real movement paths.

3. What route factor should I use?

Use 1.00 for direct movement. Use 1.10 to 1.40 for road or field movement. Higher values may fit winding routes or restricted access.

4. Does elevation affect the final distance?

Yes, elevation affects the 3D distance. The calculator adds vertical separation to surface distance. This is useful for slopes, cables, drones, and field paths.

5. Are results suitable for legal surveys?

No. Use certified survey systems for legal, aviation, emergency, or approval work. This calculator is for planning, teaching, and estimate checks.

6. Which coordinate format should I enter?

Use decimal degrees. North and east are positive. South and west are negative. Do not enter degrees, minutes, and seconds directly.

7. What does bearing mean?

Bearing is the initial compass direction from the first point to the second point. It is measured clockwise from north in degrees.

8. Can I export results for spreadsheet work?

Yes. Use the CSV button after calculating. The exported file includes labels, coordinates, elevation, surface distance, 3D distance, bearing, and travel time.
