Long Cubit
A long cubit is an ancient unit of length, slightly longer than the common cubit. Its length varied but was often around 20.6 inches.
History/Origin
The long cubit, or royal cubit, was used in ancient Egypt for monumental construction.
Current Use
The long cubit is an obsolete unit of measurement.
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.
