About Mu
The mu (亩, also written mǔ) is China's traditional unit of agricultural land area, equal to 1/15 hectare or approximately 666.67 m². It has been the standard land measurement in China for over two thousand years. China's total farmland is reported in hundreds of millions of mu, and rural property records across China use mu as the primary unit. One hectare equals exactly 15 mu. One mu equals approximately 0.165 acres or about 797 square yards.
About Barns
A barn (b) is a unit of area used in nuclear and particle physics to measure effective cross-sections of atomic nuclei and particle interaction probabilities. Equal to 10⁻²⁸ m² (10⁻²⁴ cm²), it was humorously named during the Manhattan Project - physicists joked that uranium nuclei were 'as big as a barn' at the subatomic scale. Particle physics experiments at accelerators like CERN report cross-sections in millibarns (mb), microbarns (μb), nanobarns (nb), and femtobarns (fb).
