Microinch
A microinch is a unit of length equal to one-millionth of an inch.
History/Origin
The microinch is a unit used for extremely small measurements in precision engineering and manufacturing.
Current Use
The microinch is used in fields like mechanical engineering and electronics to measure surface roughness and tolerances.
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.
