Yi (億,亿 in Chinese), oku (億, in Japanese) or eok(억 in Korean) is equal to \(10^8\)[1][2] in the Japanese, Chinese and Korean counting system. In English, it is one hundred million.

In Chinese, there was a system called "下數 (xiàshù)" where "yi" (億) means 105, zhao (兆) means 106, and so on.[3]

Yi has the same value as Myllion.
