Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
Aln
An aln is an obsolete Swedish unit of length, roughly equivalent to 2 Swedish feet or about 59 centimeters.
History/Origin
The aln was the Swedish version of the ell, a common unit of length for measuring cloth throughout Europe.
Current Use
The aln is no longer in use.
