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.
Dekameter
A dekameter is a unit of length in the metric system equal to 10 meters.
History/Origin
The prefix "deka-" from the Greek "deka" meaning ten, was part of the original metric system adopted in France in 1795.
Current Use
The dekameter is rarely used in practice. It is sometimes used in meteorology to measure altitude.
