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.


Hectare [ha]


A hectare (ha) is a unit of area commonly used in land measurement. It equals 10,000 square meters or a square that is 100 meters on each side.

1 hectare = 10,000 m² = 0.01 square kilometers.

Hectares are often used to measure fields, farms, and large plots of land.
