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.

Square Perch

A square perch is a traditional unit of area, also known as a square rod or pole. It represents the area of a square with sides one perch (rod) long.

1 perch (rod) = 16.5 feet
1 square perch = 16.5 ft × 16.5 ft = 272.25 square feet ≈ 25.29 square meters
160 square perches = 1 acre

Square perches were commonly used in land surveying and property descriptions, especially in the UK and older US records.
