Square Chain [ch²]


A square chain (ch²) is a unit of area used in land surveying, especially in the US and UK. It represents the area of a square with sides one chain long.



  • 1 chain = 66 feet (20.1168 meters)



  • 1 square chain = 66 ft × 66 ft = 4,356 square feet ≈ 404.69 m²



  • 10 square chains = 1 acre



Square chains are used to measure land parcels and agricultural fields.




Electron Cross Section


The electron cross section is a measure of the probability that an electron will interact with a target particle (like an atom or nucleus) during scattering or collision processes. It represents an effective area that quantifies the likelihood of interaction.



  • Typically measured in units called barns (1 barn = 10⁻²⁸ m²) or square meters.



  • Used in fields like nuclear physics, atomic physics, and materials science.



  • Cross sections vary depending on the energy of the electron and the nature of the target.



It helps scientists understand and predict how electrons scatter, absorb, or cause reactions at the microscopic level.
