Decimeter
A decimeter is a unit of length in the metric system, equal to one-tenth of a meter.
History/Origin
The prefix "deci-" comes from the Latin word "decimus," meaning tenth. The decimeter was part of the original metric system adopted in France in 1795.
Current Use
The decimeter is not as commonly used in everyday life as other metric units like the centimeter or meter, but it is sometimes used in technical and scientific contexts.
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.
