Acre (US Survey) [ac]


The acre (US survey) is a unit of area used mainly in the United States for land measurement, based on the US survey foot. It is slightly different from the international acre due to the foot definition.



  • 1 US survey acre = 43,560 US survey square feet



  • 1 US survey acre ≈ 4,046.87261 square meters



  • Slightly larger than the international acre by about 0.0005%.



It is commonly used in land surveying, real estate, and agriculture.



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.
