Cubit (Uk)
A cubit is an ancient unit of length based on the length of the forearm from the elbow to the tip of the middle finger. The English cubit was about 18 inches.
History/Origin
The cubit was used by many ancient cultures, including the Egyptians, Babylonians, and Romans. Its length varied from place to place.
Current Use
The 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.
