A barn is a building on a farm in which crops or animal food can be kept. Farm building used for sheltering animals, their feed and other supplies, farm machinery, and farm products. Barns are named according to their purpose (e.g., hog barns, dairy barns, tobacco barns, and tractor barns). The principal type in the U.S. is the general-purpose barn, used for housing livestock and for storing hay and grain. Most North American and European farms have one or more barns. They usually consist of two stories, though one-story barns gained in popularity in the late 20th century

A unit of area for measuring a nuclear cross section One barn equals 10-24 square centimeter
A unit for measuring cross sections 1 barn = 1024 square centimeters The units appropriate in high energy physics are usually the millibarn (10-3 barn), the microbarn (10-6), or the nanobarn (10-9 barn)
