Atlas Earth Radius Calculator

How to Use the Atlas Earth Calculator

To use this calculator, input the latitude in degrees of your location into the designated field. Then, click the “Calculate” button. The calculated result in kilometers will be displayed in the Result field.

How the Calculator Works

This calculator computes the approximate radius of the Earth at a given latitude, considering that the Earth’s radius is not constant across different latitudes due to its oblate spheroid shape. By using the cosine of the latitude in radians, it adjusts the nominal Earth radius to give a more accurate figure for the specified location.

Calculator Limitations

This calculator assumes that the Earth is a perfect oblate spheroid, which is not entirely accurate due to various geographical and geological variations, such as mountains and trenches. As such, the calculated radius should be considered approximate, and not used for precise navigational or scientific purposes.
