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.
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.
