Barn [b]


A barn (b) is a very small unit of area used mainly in nuclear and particle physics to measure the cross-sectional area of atomic nuclei and particles.

1 barn = 10⁻²⁸ square meters (m²).

The name "barn" humorously refers to something “as big as a barn” in the tiny world of atomic scales, despite its extremely small size.


Are [a]


An are (a) is a unit of area equal to 100 square meters (m²). It is commonly used in land measurement, especially in some European countries.

1 are = 100 m² = 0.01 hectares.

Ares are useful for measuring small plots of land or gardens.
