Perch
A perch is a unit of length equal to a rod, which is 16.5 feet.
History/Origin
The term "perch" has been used as a unit of measurement since medieval times and was often used interchangeably with "rod" and "pole."
Current Use
The perch 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.
