This unit (u) is based on the standard that the mass of 12C is exactly 12 u. The older symbol, [[amu]], using the standard based on the mass of 16O is no longer recommended. In biochemistry the term [[dalton]], symbol [[Da]], is sometimes used but is not here recommended. | This unit (u) is based on the standard that the mass of 12C is exactly 12 u.
