Kilometer
The kilometre (American spelling: kilometer), symbol km is a unit of length in the metric system, equal to one thousand metres and is therefore exactly equal to the distance travelled by light in free space in ⁄ 299,792.458 of a second.
It is the conventionally used measurement unit for expressing...

Gravitational metric system
In the gravitational metric system(s) the base unit of force is not normalised to one mass unit (gram or kilogram) times one length unit (metre or centimetre) per time unit squared (second) as in the SI, but it depends on a selected or locally...
International System of Units
The International System of Units (abbreviated SI from the French le Système international d'unités) is the modern form of the metric system and is generally a system devised around the convenience of the number ten. It is the world's most widely...

Astronomical units of length
The astronomical system of units, formally called the IAU (1976) System of Astronomical Constants, is a system of measurement developed for use in astronomy. It was adopted by the International Astronomical Union (IAU) in 1976, and has been slightly...
