1. What is Distance Between Cities?

The distance between cities can be measured as straight-line (as the crow flies) or driving distance (road distance). This calculator provides estimates based on geographic coordinates.

2. How Distance is Calculated

Distance calculation uses geographic coordinates (latitude and longitude) of the cities:

Where:

• Δlat — Difference in latitude between two points
• Δlong — Difference in longitude between two points
• Earth's radius — 3,959 miles or 6,371 km

Note: Driving distance uses road network data and is typically longer than straight-line distance.

3. Importance of Distance Calculation

Details: Accurate distance measurement is crucial for travel planning, logistics, fuel estimation, and route optimization.

4. Using the Calculator

Tips: Enter city names (include country for less common cities), select distance unit. For best results, use official city names.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: Accuracy depends on the data source. Straight-line distance is mathematically precise, while driving distance depends on current road data.

Q2: Why is driving distance different from straight-line?
A: Driving distance accounts for actual roads, terrain, and obstacles, while straight-line is the shortest geographic path.

Q3: Can I get distances between addresses?
A: This version calculates between city centers. For specific addresses, specialized mapping services would be needed.

Q4: What about international distances?
A: The calculator works for any cities worldwide, as long as they can be geolocated.

Q5: How current is the road data?
A: When connected to live mapping services, data is typically very current including recent road changes.
