Gigameter

A gigameter (Gm) is a unit of length in the metric system, equal to 1 billion meters (1 Gm = 10⁹ meters). Gigameters are used to measure very large distances, often within the solar system. For example, the average distance from Earth to the Sun is about 150 gigameters, or 1 astronomical unit (AU). While not commonly used in everyday life, gigameters are helpful in astronomy and space science to describe distances between planets or other celestial bodies.

Handbreadth

A handbreadth is a traditional unit of length based on the width of a human hand, typically measured from the tip of the thumb to the tip of the little finger when the hand is fully extended. It was commonly used in ancient and medieval times for everyday measurements.
