Famn
A famn is an obsolete Swedish unit of length, equivalent to 3 aln or about 1.78 meters.
History/Origin
The famn was the Swedish version of the fathom, based on the span of outstretched arms.
Current Use
The famn is no longer in use.
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.
