Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
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.
