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.
Rod
A rod, also known as a perch or pole, is a unit of length equal to 16.5 feet, or 5.5 yards.
History/Origin
The rod has been used as a unit of measurement in England since at least the 13th century. It was a convenient length for measuring land.
Current Use
The rod is now an archaic unit of measurement, though it may still be encountered in old land deeds.
