Square Decimeter [dm²]
A square decimeter (dm²) is a unit of area equal to a square with sides 1 decimeter (10 centimeters) long.
1 dm² = 0.01 m² = 100 cm².
It is commonly used to measure small surfaces, such as the area of tiles or sheets of paper.
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.
