🧭 New York, NY to Miami, FL Distance

Calculate the straight-line distance from New York, NY to Miami, FL — get instant results in kilometers, miles, and nautical miles.

This free as the crow flies distance calculator helps you measure the straight-line (great-circle) distance between two points on Earth using addresses or GPS coordinates.

Developed by glandnav.com — trusted tools for precision GPS mapping and field measurement.

🌍 What Is "As the Crow Flies" Distance?

The phrase "as the crow flies" means the shortest distance between two points, ignoring roads, terrain, or obstacles — just as a bird would fly straight from A to B.

This calculator uses the Haversine great-circle formula, a globally recognized geodesy method also applied in GPS navigation systems, to ensure accurate straight-line distance results anywhere on Earth.

⚙️ How to Measure Straight-Line Distance on Map

  1. 1
    Search or click on the map to select your starting point (A).
  2. 2
    Choose your destination (B) by clicking or entering a location or GPS coordinates.
  3. 3
    The map will automatically:
    • • Draw a straight line between A and B
    • • Display the distance in kilometers, miles, or nautical miles
    • • Show bearing (direction) and midpoint coordinates
  4. 4
    Optionally, copy coordinates or switch distance units.

💡 You can also enter latitude and longitude directly, such as:

Point A: 51.5074, -0.1278 (London)
Point B: 48.8566, 2.3522 (Paris)

Frequently Asked Questions

Find comprehensive answers to common questions and get the expert guidance you need for optimal results

What does 'as the crow flies' mean?

It means the shortest distance between two points on Earth, measured in a straight line, ignoring roads or obstacles — just as a bird would fly straight from A to B.

How is straight-line distance different from driving distance?

Driving distance follows roads and routes, while 'as the crow flies' shows the direct aerial distance, which is usually shorter.

Can I use GPS coordinates instead of addresses?

Yes. Simply input latitude and longitude values for both points. The calculator will instantly compute the straight-line distance.

How accurate is this calculator?

It uses the Haversine formula, a precise great-circle calculation method used in navigation and geodesy, accurate to within a few meters.

Can I measure distance between multiple points?

This tool currently supports two points for simplicity. For multiple-point measurements or area mapping, use https://glandnav.com/products/field-area-measure.

🧩 Technical Notes

Distance is calculated using the Haversine formula:

d = 2r * arcsin(√(sin²((Δφ)/2) + cos φ1 * cos φ2 * sin²((Δλ)/2)))
r = Earth's radius (6,371 km)
φ = latitude (in radians)
Îť = longitude (in radians)

This ensures high accuracy over any distance on Earth's surface.
