Hectometer
A hectometer is a unit of length in the metric system equal to 100 meters.
History/Origin
The prefix "hecto-" from the Greek "hekaton" meaning hundred, was part of the original metric system adopted in France in 1795.
Current Use
The hectometer is not a widely used unit of length in English-speaking countries. It is sometimes used in surveying and for marking distances on highways in some countries.
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.
