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.
Fathom
A fathom is a unit of length equal to 6 feet, used especially for measuring the depth of water.
History/Origin
The term "fathom" comes from the Old English word "fæthm," meaning "outstretched arms," as the distance was originally the span of a man's outstretched arms.
Current Use
The fathom is still used in nautical applications, especially in the United States, to measure water depth. It is also used in commercial fishing to measure the length of lines.
