Zhao (兆 in Chinese) or Chou (ちょう in Japanese) is equal to \(10^{12}\)[1] in both Japanese counting system and Chinese counting system. In English, it is equal to one trillion in the short scale and one billion in the long scale. Originally, this meant \(10^{6}\), and in Chinese this still means \(10^{6}\) in many cases.
