Review the result: The distance will be displayed along with additional information about the calculation.

The calculator uses the Haversine formula to calculate the great-circle distance between two points on the Earth's surface, providing the most accurate distance measurement possible.

Formula Used

Haversine Formula

The distance \( d \) between two points on the Earth's surface, given their latitudes \( \phi_1, \phi_2 \) and longitudes \( \lambda_1, \lambda_2 \), is calculated using the Haversine formula:

\[ a = \sin^2\left(\frac{\Delta\phi}{2}\right) + \cos(\phi_1) \cdot \cos(\phi_2) \cdot \sin^2\left(\frac{\Delta\lambda}{2}\right) \]

\[ c = 2 \cdot \text{atan2}\left(\sqrt{a}, \sqrt{1-a}\right) \]

\[ d = R \cdot c \]

Where:

\( \Delta\phi = \phi_2 - \phi_1 \)
\( \Delta\lambda = \lambda_2 - \lambda_1 \)
\( R \) is the Earth's radius (approximately 6,371 km or 3,959 miles)

This formula accounts for the Earth's curvature, providing more accurate distance measurements than simple Euclidean distance calculations.

Worked Examples

Example 1: Toronto to Vancouver

Let's calculate the distance between Toronto, Canada, and Vancouver, Canada.

Latitude of Toronto: 43.651070
Longitude of Toronto: -79.347015
Latitude of Vancouver: 49.282729
Longitude of Vancouver: -123.120738

Using the Haversine formula:

\[ \Delta\phi = 49.282729 - 43.651070 = 5.631659 \]

\[ \Delta\lambda = -123.120738 - (-79.347015) = -43.773723 \]

\[ a = \sin^2(2.8158295) + \cos(43.651070) \cdot \cos(49.282729) \cdot \sin^2(-21.8868615) \]

\[ c = 2 \cdot \text{atan2}(\sqrt{a}, \sqrt{1-a}) \]

\[ d = 6371 \cdot c \approx 3,550 \text{ km} \]

The distance between Toronto and Vancouver is approximately 3,550 kilometers or 2,206 miles.

Example 2: New York to Los Angeles

Now, let's calculate the distance between New York, USA, and Los Angeles, USA.

Latitude of New York: 40.712776
Longitude of New York: -74.005974
Latitude of Los Angeles: 34.052235
Longitude of Los Angeles: -118.243683

Using the Haversine formula:

\[ \Delta\phi = 34.052235 - 40.712776 = -6.660541 \]

\[ \Delta\lambda = -118.243683 - (-74.005974) = -44.237709 \]

\[ a = \sin^2(-3.3302705) + \cos(40.712776) \cdot \cos(34.052235) \cdot \sin^2(-22.1188545) \]

\[ c = 2 \cdot \text{atan2}(\sqrt{a}, \sqrt{1-a}) \]

\[ d = 6371 \cdot c \approx 3,935 \text{ km} \]

The distance between New York and Los Angeles is approximately 3,935 kilometers or 2,445 miles.
