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.
Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
