Azimuth (deg) 148.1

Formula: Initial great-circle bearing

Step-by-step with your numbers:

1. Values used:

2. From latitude = 51.5 deg

3. From longitude = -0.13 deg

4. To latitude = 48.85 deg

5. To longitude = 2.35 deg

7. Azimuth = 148.1deg

Did we solve your problem today?

Azimuth is the compass bearing you would follow to travel between two points.

The math behind it

It uses the great-circle initial bearing formula on the two latitude/longitude pairs.

London to Paris is a bearing of about 149 degrees (south-east).

Why 'initial' bearing?

On a sphere the bearing changes along a great-circle route, so this is the starting direction.
