Air Distance from Austin to Houston

There are several ways to calculate the straight-line (as-the-crow-flies) distance between Austin to Houston. This is also known as the great-circle distance — the shortest path between two points on the Earth's surface.

Below are two commonly used methods for calculating this distance:

Vincenty's formula (applied above)

• 148.4 miles
• 238.8 kilometers
• 128.9 nautical miles

Vincenty's formula calculates the geodesic distance between two points on the Earth's surface using an ellipsoidal model of the planet. It provides high accuracy by accounting for the Earth's flattening at the poles, making it more precise than spherical models.

Haversine formula

• 148.1 miles
• 238.4 kilometers
• 128.7 nautical miles

The haversine formula estimates the distance between two points on a sphere. It assumes the Earth is a perfect sphere, which simplifies the calculation but introduces slight inaccuracies compared to ellipsoidal models.
