Ken
The ken is a traditional Japanese unit of length, equal to six Japanese feet (shaku). Its length has varied over time, but it is now standardized at 1.818 meters.
History/Origin
The ken was traditionally used in Japanese architecture and land measurement.
Current Use
The ken is still used in traditional Japanese carpentry and architecture.
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.
