Its use is widespread in agriculture where it is more practical than either square metres or square kilometres, typical fields being a few hectares in size.

A barn is a unit of area, abbreviated mostly as "bn", equal to 10^{-28} m^{2}. Although not an official SI unit, it is widely used by nuclear physicists, since it is convenient for expressing the cross sectional area of nuclei and nuclear reactions. A barn is approximately equal to the area of a uranium nucleus.
