Fingerbreadth
A fingerbreadth is an ancient unit of length, based on the width of a finger, approximately 3/4 of an inch.
History/Origin
The fingerbreadth was a common unit of measurement in many ancient cultures.
Current Use
The fingerbreadth is an obsolete unit of measurement.
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.
