Nail (Cloth)
A nail is an obsolete unit of length, used for measuring cloth, equal to 2 1/4 inches.
History/Origin
The nail was a traditional English unit of measurement, likely deriving its name from the length of the last two joints of the middle finger.

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.
