Jerib (jarib; djerib) - regional land area
Jerib is a traditional land-area unit used across the Middle East and southwestern Asia. In modern usage it equals 10,000 m² (1 hectare) in Iran and Turkey, while in Afghanistan it is standardized at 2,000 m² (0.2 ha).
- Names/aliases: jerib, jarib, djerib
- System: Regional (non-SI; accepted alongside SI)
- Iran/Turkey (modern): 1 jerib = 10,000 m² = 1 ha ≈ 2.47105381 acres
- Afghanistan (modern): 1 jerib = 2,000 m² = 0.2 ha ≈ 0.4942 acres
- Notes: historical values varied by locale and era; verify the legal definition in deeds and surveys
- Typical examples: cadastral records, land grants, real-estate listings
Barn (b) - nuclear/particle cross-section area
Barn is a non-SI unit of area used in nuclear and particle physics to express interaction cross-sections. The name originated humorously during the Manhattan Project (“as big as a barn”).
- Symbol: b
- System: Non-SI (accepted in high-energy/nuclear physics)
- Exact relations: 1 b = 10⁻²⁸ m² = 10⁻²⁴ cm² = 100 fm²
- Common submultiples: 1 mb = 10⁻³ b; 1 µb = 10⁻⁶ b; 1 nb = 10⁻⁹ b; 1 pb = 10⁻¹² b; 1 fb = 10⁻¹⁵ b; 1 ab = 10⁻¹⁸ b
- Related usage: integrated luminosity often quoted in inverse barns (e.g., fb⁻¹)
- Typical examples: neutron capture and scattering cross-sections; collider process cross-sections reported from barns down to picobarns and femtobarns
