b to km²

barn

• Definition: The barn is a unit of area that is primarily used in nuclear physics to quantify the cross-sectional area of atomic nuclei and particles.

• Symbol: The symbol for barn is “b”.

• Usage: Barns are used mainly in scientific contexts, particularly in nuclear and particle physics, to describe the likelihood of interaction between particles, such as scattering or absorption events.

square kilometer

• Definition: A square kilometer is a metric unit of area that represents the area of a square with sides measuring one kilometer.

• Symbol: The symbol for square kilometer is “km²”.

• Usage: Square kilometers are commonly used in various fields, including geography, land planning, and environmental studies, to measure large areas of land.

Origin of the barn

• The term “barn” originated from the early 20th century and was coined by physicists. The name is believed to have been chosen humorously, likening the unit to a “barn door” that is large compared to the size of atomic particles.

Origin of the square kilometer

• The square kilometer is derived from the metric system, which was established in France in the late 18th century. It is based on the meter, which serves as the fundamental unit of length in the metric system.
