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.
